Water Testing

This kit tests tap water and aquarium water for five different parameters that affect the health of freshwater fish: pH, High Range pH, Ammonia, Nitrite and Nitrate.

The Laborett Testing Kit for freshwater and marine aquariums provides professional measurement of the most important aquarium water parameters: pH freshwater and pH saltwater, carbonate and general hardness, nitrite, ammonia and carbon dioxide.

Fresh water pH test kit with adjusting chemicals.

Includes 10 tests: Ammonia (NH3/4); Nitrite (NO2); Nitrate (NO3); pH (low range & high range kits); Carbonate Hardness (KH); General Hardness (GH); Iron (Fe); Calcium (Ca); Phosphate (PO4).

Ammonia Alert™ is an innovative color device for continuously detecting and monitoring toxic free ammonia.

Alkalinity or Carbonate Hardness (KH) is a measure of the buffering capacity of water, or its ability to resist change in pH.

The Tetratest® pH Kit was professionally developed to accurately and quickly determine the pH level in your freshwater aquarium.

pH Alert™ is a unique color device designed to be placed in the aquarium or filter and monitor pH continuously. No tests, no strips, just constant readings.

The quick and accurate way to test for pH, Nitrite, Nitrate, General Hardness and Carbonate Hardness.  Desiccant-lined tube, with snap-tight cap, provides maximum moisture protection for accurate results.

This kit measures total (NH3 and NH4+) and free ammonia (NH3 only) down to less than 0.05 mg/L and is virtually interference free in marine and fresh water.

Ammonia (NH3) is a natural, toxic by-product of animal metabolism and the decomposition of animal and plant waste materials. Without regular testing, the ammonia level in your aquarium could rise to a level that is fatal to your fish.

A complete kit for testing marine aquarium water. Tests water four ways to protect marine fish and invertebrates from dangerous water conditions. Kit includes tests for: High Range pH, Ammonia, Nitrite, Nitrate, plus four test tubes, holding tray and test tube rack. Fast, easy and accurate.

This kit measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 mg/L in marine or freshwater. MultiTest™ Nitrite. Nitrate performs over 75 tests and contains a reference sample for validation.

To maintain and grow healthy corals, the correct balance of calcium and carbonates is essential, as are low levels of phosphate and nitrate.  This kit provides highly accurate testing for each of these critical parameters:  calcium, KH, phosphate and nitrate.

One API Glass Test tube with Cap for use with API liquid test kits.

Individual Refill Bottle for Hagen Nutrafin Test Kits. Contains pH Low Range 18ml.

This kit combines the Phosphate, Silicate, and Iodine/Iodide kits into one kit. MultiTest™ Reef Special performs over 75 tests and contains a reference sample for validation.

Lil' Alert Mates™ are innovative color devices for continuously detecting and monitoring toxic free ammonia. They work just like Ammmonia Alert™ but are designed to appeal to the young aquarist. No test kits, chemicals, or procedures are needed.

Essential to be able to establish correct pH range required by fish, plants and corals (& other invertebrates). The pH value is directly implicated in ammonia toxicity. 100 tests.

Tests tap water and freshwater aquariums for general hardness (GH) and carbonate hardness (KH). Helps detect stress on fish caused by rapid pH shifts, which result from low KH levels and helps aquarists duplicate the natural habitat of their fish.

Use to measure pH changes in marine aquariums, aquariums with African cichlids, and very alkaline tap water. Reads the pH of water within the high range of 7.4 to 8.8. 160 tests per kit.

Phosphate can enter your aquarium through tap water, fish waste, and decaying organics such as uneaten food and dead algae. Excess phosphate contributes to unsightly algae blooms. This kit tests phosphate levels from 0 to 10 ppm in fresh and saltwater aquariums.
