API Aquarium Test Kit Liquid Titration Color Change Fresh/Salt Water Aquarium

Affordable Aquarium Water Testing Kits from Aquarium Pharmaceuticals Inc. Choose from 11 different tests kits.
Ammonia Test Kit
Salicylate test measures ammonia levels in both fresh & saltwater aquariums. Ammonia, the #1 killer of tropical fish, is continually produced in the aquarium from fish waste & uneaten fish food. Tests ammonia levels from 0 to 8 ppm.
Freshwater & Saltwater use
Test kit of 130 tests
Calcium Test Kit
Calcium is one of the most important elements in a reef aquarium. Reef invertebrates such as corals, crustaceans, mollusks and even some types of encrusting algae need calcium to grow and remain healthy. Over time, calcium levels drop as invertebrates use calcium in aquarium water. This kit allows you to easily and accurately measure calcium levels and maintain a healthy reef aquarium. Measures calcium levels as low as 20mg/L. Uses titration method, with easy to see color change for precise measurement. For use in reef aquariums
Saltwater use only
Carbonate Hardness KH Test Kit
Tests tap water & fresh or saltwater aquariums for carbonate hardness (KH). Helps prevent fish stress caused by rapid pH shifts, the result of low levels of KH.
Freshwater & Saltwater use
Copper Test Kit
Test reads 0 to 4 mg/L or parts per million (ppm) of copper. Helps to maintain a healthy aquarium or pond for fish by ensuring that copper (a common treatment for many parasitic infections) levels are within the healthy range. Freshwater & Saltwater use Test kit of 90 tests
Freshwater & Saltwater use
General & Carbonate Hardness(GH & KH) Test Kit
Tests tap water, freshwater aquariums & ponds 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. The general hardness (GH) and carbonate hardness (KH) of aquarium water should match that of the natural habitat of the fish. Otherwise, fish will be stressed and prone to disease. Since adding tap water increases the hardness of the aquarium water, frequent GH and KH testing is essential. This kit measures both general hardness (GH), the measure of calcium and magnesium in water and carbonate hardness (KH), the measure of carbonate and bicarbonate concentrations.
High Range pH Test Kit
High Range pH Test Kit from Aquarium Pharmaceuticals Inc. Use to measure pH changes in marine aquariums, aquariums with African chchlids, and very alkaline tap water. Reads the pH of water within the high range of 7.4 to 8.8. 250 tests per kit.
Freshwater & Saltwater use
Test kit of 160 tests
Nitrate Test Kit
Effective for both fresh & saltwater aquariums. High levels of nitrate are a food source for unwanted algae & indicate poor water quality & health problems for fish. Tests nitrate levels from 0 to 160 ppm.
Freshwater & Saltwater use
Test kit of 90 tests
Nitrite Test Kit
Tests for nitrite in freshwater & saltwater aquariums. Nitrite, toxic to fish, is produced by nitrifying bacteria in the biological filter as it breaks down ammonia.
Freshwater & Saltwater use
Test kit of 180 tests
pH Test Kit
Proper pH control is imperative to prevent the harmful effects of too alkaline or too acidic aquarium water on fish and plant life. Tests pH levels from 6.0 to 7.6. 250 tests per kit.
For freshwater use
Test kit of 250 tests
pH Test & Adjuster Kit
Enables user to adjust pH levels as required & includes 1.25 oz bottles of pH Up, pH Down, and pH Indicator Solution. Tests the pH of water within a 6.0 to 7.6 range. 250 tests per kit. For freshwater use Test kit of 250 tests
