Hello chaps!

I've just wanted to share my thoughts about general usage of ammonia/nitrite/nitrate test:

1. These test are supposed to be sensitive and qualitative. It means they inform you about possible build up of unwanted chemicals providing only rough estimate of pollutants concentrations.

2. They should be repeated at least 2-3 times to get a significant averages of pollution's level. In other words: doing single test is not enough especially when we really need as accurate as possible estimation of water parameters!. Why? Because we are playing with a complicated solution of multiple mineral substances (marine water) that can easily cross-react with ammonia/nitrite/nitrate and depending on temperature/water flow etc.. can form various salts that will obviously result in altered readings of pollutants levels!

3. Instead of looking on exact values one should pay attention to the general trends of pollutant's concentration. This is the best and most secure way to ensure our beloved reef ecosystems are in balance.

Summing up: Test kits for water quality are of extreme value. However, one has to realize that getting an accurate result from such test requires proper maintenance.
