7-in-1 Aquarium Test Strips

The 7-in-1 Aquarium Test Strips extend the 5-parameter strip format to include ammonia and chlorine detection, making them the most comprehensive single-strip water quality screening tool available for freshwater aquariums. Chlorine detection is particularly useful for detecting insufficiently dechlorinated tap water, which can kill beneficial bacteria and stress fish even in small amounts.

Ammonia detection on strips uses a colorimetric indicator that changes through yellow-green shades, distinguishing between 0, trace, 0.5, and higher readings. While less sensitive than liquid reagent tests in the 0–0.25 ppm range, the strip provides sufficient resolution to flag any urgent ammonia concern requiring liquid test confirmation.

The seven-pad format allows a full tank health check in under two minutes. The tube contains 50 strips with a desiccant cap and full-colour comparator chart printed on the packaging.
