Seachem pH Alert

$15.40
  • Continuously monitors pH in freshwater
  • No tests, no strips
  • Lasts up to 4 times as long as competing products
Seachem pH Alert is a small unobtrusive sensor with a size that is almost half and lasts up to 4 times as long as competing products. It monitors the water 24 x 7 and changes colours according to the pH level. Seachem pH Alert continually monitors the pH level of freshwater aquarium and visually alerts you by colour changes on its sensor. Simply place the Seachem pH Alert in the aquarium or filter and it will monitor pH continuously. Its sensor changes color reversibly from yellow to orange to red, alerting you to shifts in pH levels between 5.4 and 8.0. Seachem pH Alert is for Freshwater use only.

Directions

Simply place Seachem pH Alert visibly anywhere in the aquarium or filter and match the sensor color to the corresponding pH reading on the color wheel. Its that easy. No chemicals or test procedures are required. When first put in service, response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes.

Indications

No care is required beyond removing algae with a clean, soft material. Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolor the sensor. For maximum sensitivity, the unit should be read under natural daylight or daylight simulating light. Sensor exhaustion is indicated by a visible fading or washing out of sensor color. Once exhausted, it is time to replace pH Alert.

TROPICA CO2 System Nano Complete (Refill)

$23.00
TROPICA CO2 System Nano (Refill) A Plant Growth System Nano is a desirable solution for precise CO2 dosage for small aquariums. CO2 addition benefits the growth of all plants and improves colour development.
  • A complete CO2 system with an elegant nano design
  • A precise and stable CO2 regulation
  • A 3-in-1 diffuser, which ensures a maximum CO2 efficiency
How to use the product
  1. Ensure that the regulator is fully off before you mount the regulator on the CO2 cartridge.
  2. Fill the diffuser-chamber with water.
  3. Place the cartridge in the rack, slide the suction cups on the hose and mount the hose to the regulator and the diffuser.
  4. Mount the diffuser with the suction cups at the inner side of the tank near the bottom and place the hose in the back corner.
  5. Leave the diffuser for 24h in the tank to ensure that the ceramic disc is fully moistened.
  6. Open the regulator carefully and count the number of bubbles per minute in the diffuser-chamber.
  7. Wait 5 minutes, adjust and repeat until the number of bubbles per minute is similar to the recommendation in the table.
  The table shows recommended dosage (bubbles per minute) in different tank sizes. A 95 g CO2 cartridge contains 50,000 ml CO2. The most important nutrient for plants is CO2. The natural CO2 level in an aquarium is 0-0.5 mg/L of water. Even the slightest addition of CO2 can make a big difference improving the growth and vigour of the plants. If the aquarium contains only slow-growing  Easy-plants, the addition of CO2 gas into the water should reach a level of approx. 3 mg/L to ensure good growth conditions. For Medium category plants the CO2 requirement is approximately 10 mg/L and for Advanced plants approx.  25 mg/L. *) If you have a larger aquarium containing   Medium or Advanced plants, the lifetime of a nano-cartridge will be too short. In this case we recommend a larger cylinder e.g. 2 kg refillable. All figures are approximate.
