I've never been one for testing water in my tank but I bought a kit after setting up the new tanks, I don't know what's acceptable in planted tanks but I got 1.2mg/l of ammonia today??? I know ammonia should be zero so I'll be doing water changes till the substrate stops leeching but what are acceptable levels of nitrate and nitrite in a planted tank being dosed with TPN+ and excel??? My test kit measures in mg/l?
