The API Master Test Kit is the liquid reagent set most people start with, and the one a good many fishkeepers still have in the cupboard years later.
Key features
Liquid reagents read against a printed colour card, which resolves finer differences than a dip strip
Glass test tubes and instructions included, so nothing else is needed to begin
Freshwater, saltwater and reef versions, each built around the parameters that matter for that system
Enough reagent for a long run of testing, which works out cheaper per test than strips
Options
Freshwater — the core cycling parameters, including pH, ammonia, nitrite and nitrate
Saltwater — the same ground adapted for marine water
Reef — parameters a reef keeper tracks, including calcium, carbonate hardness, phosphate and nitrate
The single most useful thing this kit tells you is that ammonia and nitrite read zero. In an established tank they should, and when they do not, something has gone wrong with the biological filter. Testing matters most while a new tank is cycling, in the weeks after adding stock, and any time the fish look off.
The rest of the API line is in our API collection. Available for pickup at our Lethbridge store.
