sera ammonium/ammonia-Test (NH4/NH3)

NITRITE FRESHWATER TEST KIT Colombo Aquarium Nitrite Test Kit, Nitrite (NO2) is produced from the breakdown of ammonia in the filter. Nitrite is highly toxic to fish, but is usually removed from the water by the bacteria which live inside the filter. However, in new ponds and aquariums, or if the filter bacteria are damaged, the nitrite level may become toxic. The only way to know what the nitrite level is by testing the water with a Nitrite pond test kit. A regular testing, especially in new aquaria and ponds, will prevent damage caused by nitrite poisoning. An optimal level of nitrite in any tank or pond is simply 0mg/l, when the nitrite level is 0.5 mg/l or higher it means there are not enough bacteria present. Colombo have produced test kits that are developed especially for freshwater. These tests give the best results!   Colombo, 30 years of experience, that makes the difference.

Phosphate FRESHWATER TEST KIT Phosphate levels would rise in aquariums that are not properly maintained and contribute to high algae growth. Testing for phosphates and learning about the sources of phosphate in your aquarium water will help you combat their effects. Phosphate sources includes :

• Uneaten food
• Plant decay
• Dying algae
• Fish feces
• Dead fish
• etc

PO4 MARINE WATER TEST KIT Phosphate (PO 4) is one of the waste products left over after the fish the food is digested. Phosphate is not toxic to fish and therefore not a direct problem.Indirectly phosphate can take care of algae problems. Although it is not toxic, it is associated with unwanted algal growth would be desirable to keep the phosphate content. In freshwater, we recommend to keep the phosphate concentration below 1.0 mg / l, and in seawater at 0 mg / l . This can change the best water.

• 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.
