Tetra Test Kits
Water tests by Tetra
Tetra Test Kits are liquid kits, which works by changing the colour of a water sample in relation to the concentration of a given substance. You simply need to compare the colour of the sample to the easy-to-read colour charts, or count the number of drops it takes to alter the colour of the sample. Always read the instructions carefully before use. If levels are unsatisfactory then you should seek advice as to the underlying cause.
