Condition. Test. Treat. Maintain.
Good water is a routine, not a rescue. The API range is built around a simple loop that keeps parameters where fish need them — and every step has a product on this site.
Condition
Tap Water Conditioner and Stress Coat neutralise chlorine and chloramine and detoxify heavy metals the moment new water goes in.
Test
The Freshwater Master Test Kit and the 5-in-1 strips read pH, ammonia, nitrite and nitrate — the invisible numbers that decide fish health.
Treat
Quick Start seeds the filter with live nitrifying bacteria; Melafix, Pimafix and Super Ick Cure deal with infections when they appear.
Maintain
Stress Zyme keeps the filter bed working, Accu-Clear polishes the water, and Bio-Chem Zorb, Nitra-Zorb and Phos-Zorb pull problems out of it.
Why API
Getting water right since 1963
Since 1963
Aquarium Pharmaceuticals opened in Pennsylvania in 1963 and has worked on one problem ever since: keeping aquarium and pond water healthy for the fish in it.
30+ global patents
API's own research scientists pioneered treatments the hobby now takes for granted — from ammonia detoxifiers to the liquid reagent tests that read water accurately.
Test, then treat
Liquid test kits read the water precisely; conditioners and remedies fix exactly what the test finds. Clear dosing on every bottle means no guessing and no overdosing.
Made for stocked tanks
Dosed as directed, API conditioners, clarifiers and filter media are designed to go into a tank with the fish and plants still in it — you treat the water, not the fish.
