So my tank is closing in on two years. I have never tested for nitrate because I’ve battled it for years, and just did not think low levels would be an issue. After finally getting a Salifert nitrate kit my reading are 0 clear as water. So I ordered nitrate and will start dosing to try to get it to 2ppm, is that correct? Do I have to bring it up slowly as not to stress the fish, and if so how do I figure the amount to dose? I would of never thought nirate would be a limiting factor In my tank.
