The main factor in successful fish keeping and health lies in the maintenance of good water quality. Ammonia, nitrite and pH levels in the aquarium should be checked regularly. The Aquarium Lab Multi-Test Kit comprises up to 200 tests combined of the 6 key parameters to test in your aquarium: ammonia, nitrite, nitrate, pH, GH and KH. All the tests are liquid drop tests from a dropper bottle so all the drops are the same size. Full instructions are included detailing optimum levels and suggestions for correction, along with an integrated test tube rack. All you have to do is add your aquarium water to the test tube and count the drops needed. The back of the box details clear pictorial instructions so you can see what to do from the start. A set of colour-coded stickers is provided to label both the test tubes and test tube lids so you always conduct the same test in the same test tube avoiding contamination.

This test kit reports concentration in terms of nitrogen (NH3-N), (NO2-N) or (NO3-N) to be compatible with reported safe concentrations as they apply to fish and plants. If you are interested in knowing the ionic concentration of the measured parameter, multiply your result by 1.21 (NH3-N), 3.29 (NO2-N), or 4.43 (NO3-N).
