How type of plants food I can use in my tank which will not change quality water.
I keep Discus and the water have to be : pH 6, KH near 0, GH near 1.
Till one month ago I used Plants Food from Giovanni. Plants growin up so quickly - Cabomba near 20cm per week, but the quality water was not good for Discus. I stopes to put this treatment and now all plants is not really good condition
Have somebody know any Plants Food Company what after using the pH, KH, GH will not change ?
Please for advice
