Seachem Alkaline Buffer

$14.90$50.00
  • Adjusts pH to 7.2—8.5
  • Increases alkalinity
  • Contains no phosphate

Description

Alkaline Buffer™ is a non–phosphate buffer to raise pH and alkalinity (KH) and buffer with Acid Buffer™. These buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem. Alkaline Buffer™ raises pH and buffers between 7.2 and 8.5. It is gentle, safe, and enhances the freshwater environment.

Directions

To increase pH, use 1 teaspoon (6 g) for every 80 L (20 gallons) daily until desired pH is reached (this dose raises alkalinity by about 1 meq/L (2.8 dKH)). For precise dosing, use the Seachem Digital Spoon Scale. In order to adjust pH gradually, use Alkaline Buffer™ with Acid Buffer™. When using Alkaline Buffer™ & Acid Buffer™ together to target a specific pH, utilize the suggested ratio chart.
This chart is based on use in RO or RO/DI water and ratios may need to be adjusted for use in tap water. HINT: First determine the amount of Alkaline Buffer™ needed for the volume of water. This should be determined based upon your desired alkalinity (KH). Then, divide by the number in the middle column to obtain the correct amount of Acid Buffer™ required.

Seachem Malawi/Victoria Buffer

$14.40$45.90
  • Buffers to pH of 7.8 - 8.4
  • Raises KH and pH
  • Does not affect GH
Malawi/Victoria Buffer resets water pH to 7.8 - 8.4, delivers carbonate salts, raises carbonate hardness and creates ideal environment for cichlids to thrive. It is formulated to maintain a pH of 7.8 to 8.4. For optimum replication of the Malawi/Victoria Lake environment, use with Cichlid Lake Salt, Cichlid Trace, and NutriDiet Cichlid Flakes.

Directions

Use 6 g (one level teaspoon) for each 40 to 80 L (10 to 20 US gallons) of water each day until desired pH is attained and maintained. Thereafter, use as required to maintain pH, usually no more than once every two to three weeks. For precise dosing, use the Seachem Digital Spoon Scale. TIPS: It is best to dissolve the buffer in freshwater before use. Use when setting up an aquarium or making water changes (preferably after the addition of Seachem Cichlid Lake Salt) and between water changes as needed to maintain pH. Seachem Malawi/Victoria is formulated to maintain a pH between 7.8 and 8.4, depending on the amount used. To attain a lower pH than 7.8, you may use Seachem Acid in combination with Malawi/Victoria. To attain a higher pH than 8.4, use Tanganyika.

Seachem Reef Buffer

$14.40$45.00
  • Raises pH to 8.3
  • Raises pH and carbonate alkalinity together
  • pK (8.6) allows for greater pH stability in a reef system where the bioload is significantly more than in a fish only system
Made from a proprietary blend of carbonate and bicarbonate salts, Seachem Reef Buffer lets you safely raise the pH of your reef system to pH 8.3 without danger of overdosing. When used as directed, Seachem Reef Buffer will raise the pH of your reef system to the maximum of 8.3. This blend of salts results in Seachem Reef Buffer yielding a pK of roughly 8.6 in saltwater.

Stable pH - Thriving Reef Tank

Seachem Reef Buffer lets you safely raise the pH of reef system to 8.3 without danger of overdosing. It stabilises the pH, ensures a thriving reef tank.

pH and pK

The pK of a buffering agent is equivalent to the pH around which that buffer most strongly buffers. One would presume, then, that the pK of a saltwater buffer should be 8.3; however, the multitude of organic acids produced by the inhabitants of a reef system forces pH downward to a much greater degree than in a non-reef, marine system. A buffer with a pK of 8.3 would end up yielding a pH more in the range of 8.0-8.2. Seachem Reef Buffer has higher pK (8.6) which allows for greater pH stability in a reef system where the bioload is significantly more than in a fish only system. Competing products are not designed specifically for the reef environment, so their pK is too low (in most cases, pK 8.3). At this pK, the proper pH can never be reached in saltwater. Seachem Reef Buffer will also raise carbonate alkalinity; however, when pH is not an issue, Reef Builder or Reef Carbonate should be your first choice for a carbonate alkalinity supplement.

Directions

Check pH and alkalinity before use (use MultiTest Marine pH and Alkalinity to test ph nd alkalinity levels). Use 5g (1 level teaspoon) for every 150L (40 US gallons) to raise pH by about 0.1 pH units (this will also raise alkalinity by about 0.5 meq/L). For precise dosing, use the Seachem Digital Spoon Scale. Dissolve in at least 250 ml (one cup) of freshwater, then add to the tank. The pH of natural sea water is 8.258.30. In a well established reef system pH adjustment may be necessary biweekly to semiweekly. Dosing requirements will vary, but do not exceed the recommended dose without checking your pH and alkalinity (alkalinity should not exceed 6 meq/L). If an alkalinity of 6 meq/L has been reached and a pH of at least 8.20 has not been attained or substantial cloudiness that does not clear within 15 minutes is encountered, then the system is not ionically balanced. To restore ionic balance perform a water change or adjust the magnesium and calcium levels to approximately 3:1 Mg:Ca. DO NOT OVERDOSE: Excess alkalinity may enhance the loss of calcium, magnesium, and strontium. Do not directly mix with any calcium, magnesium, or strontium supplement. Best if calcium and carbonate additives are added on alternate days or at least 30 minutes apart.

Seachem Acid Buffer

$14.90$50.00
  • Adjusts pH to 5.0—8.0
  • Converts alkalinity [KH] to CO2
  • Contains no phosphate

Description

Acid Buffer™ is a non–phosphate buffer to lower pH and buffer with Alkaline Buffer™. Both buffers are designed for the planted aquarium or for very hard water where phosphate buffers may pose an algae or cloudiness problem. Acid Buffer™ lowers pH and buffers between 6.0 and 8.0 when used with Alkaline Buffer™. As Acid Buffer™ lowers pH it converts carbonate alkalinity (KH) into available CO2.

Directions

To lower pH, use 1/4 teaspoon (2g) for every 80 L (20 US gallons) daily until desired pH is reached (this dose lowers alkalinity by about 0.2 meq/L (0.6 dKH)). Larger doses may be required in very hard (KH) or alkaline waters. For precise dosing, use the Seachem Digital Spoon Scale. In order to adjust pH gradually, or if water is soft or not well buffered, use Acid Buffer™ with Alkaline Buffer™. When using Alkaline Buffer™ & Acid Buffer™ together to target a specific pH, utilize the suggested ratio chart.
This chart is based on use in RO or RO/DI water and ratios may need to be adjusted for use in tap water. HINT: First determine the amount of Alkaline Buffer™ needed for the volume of water. This should be determined based upon your desired alkalinity (KH). Then, divide by the number in the middle column to obtain the correct amount of Acid Buffer™ required.

Seachem Cichlid Lake Salt

$15.70
250g
  • Replicates the environment of African Cichlids
  • Contains proper amounts of calcium, magnesium, sodium, and potassium
  • Affects hardness only, not alkalinity or pH

Description

Cichlid Lake Salt™ is a chemically sound blend of salts designed to replicate the natural environment of Rift Lake African Cichlids. It contains all physiologically essential elements such as magnesium, calcium, sodium, potassium, and includes trace components such as iron, aluminum, and iodide. Although the major Rift Lakes contain basically the same mineral salts, they do so in greatly differing concentrations. Cichlid Lake Salt™ is formulated so that dosages vary depending on the lake of origin and need only be added when setting up an aquarium or with water changes. Many competing products are little more than combinations of Epsom salt and bicarbonate of soda. This will not provide a complete replication of the mineral salts that are contained in the lakes of Africa, in particular calcium and potassium. Seachem’s Tanganyika Buffer™ (pH 9.0–9.4) and Malawi/Victoria Buffer™ (pH 7.8–8.4) should be used to adjust carbonate hardness and pH.

Directions

All doses given for 40 L (10 US gallons).
  • Tanganyika: Use 11 g (1.5 teaspoons).
  • Malawi: Use 5.5 g (3/4 teaspoon).
  • Victoria: Use 3.6 g (1/2 teaspoon).
Dosages are based on DI or RO water; for other water, measure hardness (GH) first, then add according to need. For reference, the Tanganyika dose raises dGH by 8.8 units. The Malawi dose raises dGH by 4.4 units. The Victoria dose raises dGH by 3 units. We recommend the following GH ranges:
  • Tanganyika: 3–5.5 meq/L (8–14 dGH)
  • Malawi: 1.5–3meq/L (4–8 dGH)
  • Victoria: 1–2 meq/L (3–6 dGH)
TIPS: Use when setting up an aquarium and when making water changes. To add salt to an established tank, base dose on water being changed. Do not use salt when simply replacing evaporated water. It is best to dissolve the salt in freshwater before use.
CAUTION: Causes serious eye irritation. Keep out of reach of children. Avoid contact with skin. May cause skin burns. Wear suitable gloves

Seachem Flourish Trace

$8.40$64.70
  • Trace elements supplement for the planted aquarium
  • Allows for more frequent dosing than a broad spectrum supplement without worrying about a build up of more slowly used components

Description

Flourish Trace™ supplies a broad range of trace elements demonstrated to be necessary for proper plant health and growth (see below for signs of deficiencies). Trace elements are normally depleted by utilization, oxidation and precipitation. The latter two processes occur more rapidly than with other micronutrients. This makes it important to restore trace elements on a regular basis. Flourish Trace™ may be used alone or in conjunction with Flourish®. Best results are obtained when both are used. Flourish Trace™ is safe for invertebrates such as shrimp.

Signs of Trace Element Deficiencies

  • Boron: Death of stem and root apical meristem, leaves twisted, young tissue most affected
  • Cobalt: used for nitrogen fixation, same as nitrogen deficiency signs (stunted growth)
  • Copper: Young leaves dark green, twisted, wilted, tip remains alive
  • Manganese: Chlorosis of young leaves, with smallest veins remaining green, necrosis between veins
  • Molybdenum: Chlorosis, twisting, death of young leaves
  • Zinc: Reduced leaf size, shortened internodes, chlorosis, spotted leaves, older leaves most affected<
  • Nickel: lack of germination or seed formation, required for iron absorption

Directions

Use 1 capful (5 mL) for every 80 L (20 US gallons) twice a week. When using in conjunction with Flourish®, dose on alternate days.

Seachem Flourish Potassium

$10.30$152.90
  • Potassium supplement for the planted aquarium
  • Highly concentrated (50,000 mg/L)
  • Does not contain phosphate or nitrate making it ideal for use with Flourish Nitrogen and Flourish Phosphorus

Description

Flourish Potassium™ contains 50,000 mg/L of potassium suitable for the natural planted aquarium. Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases potassium could become the limiting factor to growth. Use Flourish Potassium™ to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth. The most easily obtained sources of potassium are potassium nitrate and potassium phosphate. Both of these sources add to either nitrogen or phosphorus as well as potassium, making it virtually impossible to target a specific NPK ratio. Flourish Potassium™ is derived from potassium sulfate, allowing the user to adjust potassium levels without affecting nitrogen or phosphorus.

Directions

Use 1 capful (5 mL) for every 125 L (30 US gallons). This dose raises potassium by 2 mg/L. Repeat 2–3 times per week or as needed in response to signs of potassium deficiency in older leaves which include: chlorosis (yellowing), necrosis (death/browning), pinholes in leaves, and weak stems and roots.

Seachem Flourish Phosphorus

$11.30$78.50
  • Phosphorus supplement for the planted aquarium
  • A safe 4500 mg/L solution of potassium phosphate
  • Takes the guesswork out of phosphate dosing

Description

Phosphorus is one of the main three macro nutrients (nitrogen, phosphorous, potassium: NPK) required by plants and can often become the limiting factor to growth in a flourishing system. Flourish Phosphorus™ is a safe solution (4,500 mg/L phosphate) of potassium phosphate that takes the guess work out of phosphate dosing. Unlike competing products that mix nitrate and phosphate in a fixed ratio, Flourish Phosphorus™ (being nitrate free) allows you to dose phosphorus according to the needs of your plants without the risk of overdosing nitrates. When used as directed, Flourish Phosphorus™will enhance and accelerate the growth of aquatic plants without enhancing algae growth. For maximum benefit, use with Flourish Nitrogen™ and Flourish Potassium™. Flourish Phosphorus™ is safe for invertebrates such as shrimp.

Directions

BEGINNER: Use 2.5 mL (half a cap) for each 80 L (20 US gallons) once or twice a week or as needed in response to signs of phosphorus deficiency (e.g. stunted growth, plant dark green). EXPERT: The beginner dose raises phosphorus by 0.05 mg/L (0.15 mg/L phosphate). The ideal phosphate level will vary, but generally ranges from 0.15–1.0 mg/L. Use MultiTest™: Phosphate to monitor phosphate levels. To target a specific phosphate increase, dose according to the following formula: 0.8vp=m, where v= volume of tank in gallons, p=desired phosphate increase and m=volume of product to use in mL. For example to raise 20 gallons to 0.1 mg/L phosphate you would use: 0.8*20*0.1=1.6 mL.

Seachem Flourish Nitrogen

$10.30$78.50
  • Nitrogen supplement for the planted aquarium
  • 15,000 mg/L blend of nitrogen sources
  • Provides nitrogen in both the nitrate form and the ammonium form

Description

Nitrogen is one of the main three macro nutrients (nitrogen, phosphorus, potassium: NPK) required by plants and can often become the limiting factor to growth in a flourishing system. Flourish Nitrogen™ is a concentrated (15,000 mg/L) blend of nitrogen sources. It provides nitrogen in both the nitrate form and the plant–preferred ammonium form. However, no free ammonia is released because the ammonium in Flourish Nitrogen™ is complexed and unavailable until utilized by the plants. Flourish Nitrogen™ also provides nitrate for those plants that can readily utilize nitrate as well. For maximum benefit, use with Flourish Phosphorus™ and Flourish Potassium™. Flourish Nitrogen™ is safe for invertebrates such as shrimp.

Directions

BEGINNER: Use 2.5 mL (half a cap) for each 160 L (40 US gallons) twice a week or as needed in response to signs of nitrogen deficiency (e.g. stunted growth, chlorosis). For smaller doses, please note that each cap thread is approximately 1 mL. EXPERT: The beginner dose raises nitrogen by the same degree that 1 mg/L nitrate would. This dose is sufficient to provide approximately 4 g of growth (dry) or about 20 g (hydrated) over a 1 month period (assuming all other necessary nutrients are provided). For increased growth use proportionately more. To target a specific nitrogen increase, dose according to the following formula: 0.25vn=m, where v= volume of tank in gallons, n=desired nitrogen increase (if using a “nitrate equivalent” value for “n” then use a factor of 0.05 instead of 0.25 in the formula) and m=volume of product to use in mL. For example to raise 20 gallons by 0.20 mg/L nitrogen you would use: 0.25*20*0.20=1 mL. Because one-half of the nitrogen in Flourish Nitrogen™ is from nitrate you can get a reasonable estimate of nitrogen levels by doubling a nitrate reading.

Seachem Flourish Iron

$8.40$64.70
  • Highly concentrated (10,000 mg/L)
  • Ferrous gluconate iron
  • Ferrous gluconate is better suited to foliar feeding than iron-EDTA

Description

Iron is immobile in plants. This means that plants cannot divert iron from older leaves to new ones. Therefore, deficiency symptoms appear first on new or young leaves. Because plants use iron to produce chlorophyll, a lack of iron results in chlorosis, or yellowing, of the younger leaves. Stems may also appear short and slender. If the deficiency is severe and prolonged, each new leaf emerges lighter in color than the preceding leaf. When choosing an iron supplement, it is important to know the distinction between the two forms of iron. The iron will be in one of two oxidation states: ferrous having a +2 charge, or ferric having a +3 charge. Ferrous iron, the preferred iron form and is soluble in water at any pH. Ferric iron, however, is only soluble below a pH of around 5.5; but if the pH is higher than 5.5, which more than likely it will be in a planted aquarium, the ferric iron will become insoluble and precipitate, settling in the root zone. Once this occurs, foliar absorbtion becomes impossible. To overcome this precipitation, competing products employ a chelate of ferric iron: iron-EDTA. While this does keep it soluble, it has a couple of drawbacks with respect to foliar uptake of iron. (1) Iron-EDTA bonding is very strong, thus very little of the iron will be available to the plants over a given time frame and (2) Physiological energy must be expended by the plant in order to extract the ferric iron from EDTA-iron and then convert (reduce) it to the ferrous form. Our approach is different in that we use a complex (not chelate) of ferrous iron in Flourish Iron™. Flourish Iron™ is a highly concentrated (10,000 mg/L) ferrous iron gluconate supplement. Plants are able to much more easily derive a benefit from Flourish Iron™ because ferrous iron gluconate is already in the ferrous form so they do not expend energy reducing it. Despite what other manufacturers may intimate, gluconate is not harmful to plants or fish. In fact, ferrous gluconate is better suited to foliar feeding than is iron-EDTA owing to the relatively weaker iron-gluconate bonding vs. iron-EDTA bonding. In addition, ferrous gluconate has the added bonus of being a source of carbon.

Directions

Use 1 capful (5 mL) for each 200 L (50 gallons) or as required to maintain about 0.10 mg/L iron. For smaller doses please note that each cap thread is about 1 mL. Use MultiTest®: Iron test kit to monitor iron concentrations. Due to rapid utilization, test within 30 minutes. Use as needed to combat signs of iron deficiency (usually seen in new growth) which include: chlorosis (yellowing) of tissue between veins and short and slender stems.

Seachem Flourish Excel

$10.30$152.80
  • Bioavailable organic carbon source for the planted aquarium
  • Use as an alternative to CO2 injection or in addition to it
  • Introduces photosynthetic intermediates

Description

Flourish Excel™ is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO2, but, may also be derived from simple organic compounds (such as photosynthetic intermediates). The use of either CO2 injection or Flourish Excel™ does not necessarily negate the use of the other. Because the processes of producing photosynthetic intermediates and building onto them occur simultaneously, one can derive a substantial benefit with the use of Flourish Excel™ either alone or in conjunction with CO2 . The combination is particularly ideal for situations when continuing to add CO2 could result in dangerously low pH levels. Flourish Excel™ also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3). The reason plants need CO2 is to produce longer chain carbon compounds also known as photosynthetic intermediates. Photosynthetic intermediates includes compounds such as ribulose 1,5-bisphosphate, and 2-carboxy-3-keto-D-arabinitol 1,5 bisphosphate. Although the names are complicated, the structures are quite simple (5 carbon chains). Flourish Excel™ does not contain these specific compounds per se, but one that is quite similar. By dosing with Flourish Excel™ you bypass the involvement of CO2 and introduce the already finished, structurally similar compounds. It is in its structural similarity that Flourish Excel™ is able to be utilized in the carbon chain building process of photosynthesis. Simple chemical or enzymatic steps can easily convert it to any one to any one of the above named compounds (or a variety of others).

Directions

On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 US gallons). Thereafter use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL. DO NOT OVERDOSE
CAUTION: Do not eat drink or get into eyes. In case of eye exposure, promptly & thoroughly wash eyes with water & seek medical attention.
