Explore Australian-made Aquasonic aquarium water test kits at The Tech Den. Choose individual tests for pH, general hardness, carbonate hardness, ammonia, nitrite, nitrate and phosphate, with freshwater and marine suitability varying by kit.

Freshwater pH and hardness tests

Browse Aquasonic General Hardness (GH) for freshwater aquariums and Carbonate Hardness (KH) for freshwater and saltwater use. The range includes a standard freshwater pH kit and a high-range freshwater pH kit. Check the measurement range on the packaging and instructions to choose the appropriate pH test for your water.

Ammonia, nitrite and nitrate testing

Aquasonic ammonia, nitrite and nitrate kits are listed for freshwater or marine aquariums. Each measures a different parameter, so select the tests needed for your aquarium rather than treating these kits as interchangeable. The listings indicate approximately 60 ammonia tests, 85 nitrite tests and 35 nitrate tests per kit.

Phosphate testing

The Aquasonic phosphate kit is listed for freshwater or saltwater use and measures inorganic phosphate (PO4). The listing indicates approximately 95 tests. Follow the product's instructions for sample preparation, timing and reading the result.

Choose and use your test kit

Match each kit to your aquarium type and the parameter you want to measure. GH and KH kits list approximately 85–125 and 125–250 tests respectively, with the number of tests varying according to the water being tested. Follow the supplied instructions, check reagent expiry dates and record readings to compare changes over time. Verify any unclear measurement-range information on the product packaging before use.
