Product Description Nitrite is a substance that is toxic to fish and invertebrates.It is a misconception that once a tank is through its cycle (first 3 or 4 weeks) that nitrite has vanished.Many nitrite test kits suffer from interference by amines (such as naturally occurring and essential amino acids) resulting in a too low measured value especially if the nitrite concentration is relatively low.Nitrite is converted to nitrate in properly cycled aquariums.The thus formed nitrate is transformed into harmless nitrogen gas (=denitrification).This happens in areas deprived of oxygen within live rock and miscellaneous filter materials.Before it can be transformed to nitrogen gas the nitrate is first converted back to nitrite.When for whatever reason this particular cycle can not be completed, toxic nitrite can be present in significant concentration and readily be detected by test kits that do not suffer from amine interference.Conclusion:Many nitrite test kits have the potency to suffer from amine interference resulting in toxic nitrite not being detected.Salifert’s Nitrite test kit does not suffer from such an amine interference because very special ingredients are used.These same ingredients also result in a full color development within minutes.The developed color is very intense making detection of even minute traces of nitrite easy.It probably is the most sensitive, accurate and fastest nitrite test kit available.

Product Description A too high nitrate concentration can result in unwanted algae-growth and these might irritate corals in their neighborhood. Nitrate as such also retards coral growth. The nitrate concentration in a proper functioning reef aquarium should preferably be lower than 1 mg/L. Fish-only aquariums would usually show much higher nitrate concentrations. Most test kits use a procedure in which a certain part of nitrate is converted chemically into nitrite and is measured as such. Once again, just as with nitrite testing, amine interference has a major impact on the measured value. If such an interference occurs concentrations much lower than actual will be measured.  Conclusion: Many nitrate test kits are prone to amine interference. This can give results much lower than actual. The Salifert nitrate test does not suffer from such an amine interference. The very special ingredients allow a very fast and precise measurement. The range spans from very low to a very high nitrate concentration (approx. 0.05 – 20 mg/L as Nitrate-Nitrogen or 0.2 – 100 mg/L as nitrate ion). The kit can perform approx. 60 measurements. When an aquarium has insufficient regions deprived of oxygen (= anaerobic zones) or denitrification proceeds incompletely then nitrate will build-up. A too high nitrate concentration can result in unwanted algae-growth and these might irritate corals in their neighborhood.

Product Description For Fresh and Saltwater Ammonia and ammonium are substances which should be converted rapidly into nitrite followed by nitrate and nitrogen gas.If this does not happen then the aquarium is not fully cycled or biological processes are not proceeding as they should.The Salifert Ammonia test is very straightforward and measures the sum of toxic ammonia and ammonium in just a few minutes.The kit can perform approximately 50 measurements and can detect 0.5 ppm of total ammonia easily.

ZAIR.  Zero, Add, Insert, Read. *To zero 1 ml of reagent A is added to deionized/distilled water as a blank. Features at-a-glance: Easier to use and more accurate than chemical test kits Dedicated to a single parameter Small size, big convenience Ideal for: Aquaculture, Water Quality, Environmental, Education Includes: HI758 Calcium Checker is supplied with (2) sample cuvettes with caps, calcium reagent starter kit for 25 tests, dropper, (2) 1 ml syringes with tips, battery, instructions and quick start guide. Calcium Checker Troubleshooting Tips Never rinse your cuvettes with tap water or saltwater Use pure vapor distilled water from your local pharmacy at C1 phase. RODI water from home filtration units may not be suitable for this test as calcium can easily permeate through your filter membranes. Even though your TDS meter may read "zero" that number is subjective as you have to factor in the accuracy statement of the meter itself and if your storage reservoir has been contaminated. Clean your cuvettes with distilled or deionized water absent of Calcium that is going to be used for C1 phase dilution. Measure out 9 ml of distilled or deionized water for C1 phase Make sure no excess aquarium sample saltwater is on the tip of the pipette. Only administer the saltwater that is sucked into the pipette tip.

Product Description Aquaforest give accurate results when testing Magnesium - test kit will give 55-60 tests per kit.Magnesium Test KitAquaforest TestPro Magnesium is designed to quickly measure the concentration of Magnesium (Mg) in marine water. Magnesium plays an important role in many biological processes, e.g. takes part in the construction of hard coral’s calcium carbonate skeleton. Due to its unique chemical properties it has significant impact on seawater buffering capacity, and also prevents excessive precipitation of calcium carbonate on aquarium equipment. Adequate level of Magnesium is crucial in maintaining proper Calcium and Alkalinity balance in reef aquaria. Mg levels should be analysed regularly, together with other critical water parameters like Calcium and Alkalinity. The concentration of Magnesium in natural seawater is between 1260-1460 mg/l (ppm). Test Kit contains sufficient reagents to perform approx. 55-60 separate tests within that range.

Product Description The Alert Combo™ pack combines Ammonia Alert® (1 card) and pH Alert® (1 card). Ammonia Alert® and pH Alert® are almost half the size of competing products. At 1.5" x 2.5", they are small, clear, and unobtrusive, so they won't detract from the view of your aquarium. Simply place Ammonia Alert® and pH Alert® visibly anywhere in the aquarium or filter. It’s that easy. No chemicals or test procedures are required. Ammonia Alert Ammonia Alert's® sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. It detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia. Marine or freshwater use. pH Alert pH Alert® is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. A sensor changes color reversibly from yellow to orange to red alerting you to shifts in pH levels between 5.4 and 8.0. When first put in service, pH Alert® response time will be about 30 minutes. Thereafter, pH shifts will register within ten minutes. Freshwater use only.

Product Description Ammonia Alert® is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. This product is not recommended for use at acid pH. Marine or freshwater use. In the absence of free ammonia the unit will assume a yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia. Ammonia Alert® lasts over 9X as long as competing products. Ammonia Alert® is also almost half the size of competing products. It's small, clear, and unobtrusive, so it won't detract from the view of your aquarium. No care is required beyond removing algae with a clean, soft material. Avoid touching the sensor with fingers, since skin oils can damage it. Do not use bleach, soap, detergents or hard objects to clean the sensor. Some dye medications may discolor the sensor. Sensitivity improves with age, provided the unit is not allowed to dry out, however, drying does not permanently impair the unit. For maximum sensitivity, the unit should be read under natural daylight or daylight simulating light. Red enhancing light minimizes green and blue hues, decreasing the apparent sensitivity of the unit. The response of the unit may be checked by holding it briefly over the mouth of an ammonia bottle: color should develop rapidly.
