Salifert Profi test Organics
Some organic compounds, such as phenols / humic acids, are not removed efficiently by skimming, biological filtration or activated carbon. These compounds can be insensitive (difficult to remove), which is considered a negative effect on water quality. The Salifert Organics test is a semi-quantitative measure of such compounds, and no other manufacturer offers such a test kit. Number of tests depends on the degree of contamination, but an average of 50 tests per package can be assumed.
