I have a 55w AH supply retrofit over my 33g tank for 1.66 wpg and prior to adding regular large doses of excel, I was having constant BBA and GSA issues. Even with 20 ml of excel a day, I still have some BBA (and my vals hate me).
I had a similar situation until I dosed with diluted solution of KNO3 for a week. I think this balanced the ecosystem because my tap water is high in phosphates, has no gh or kh. I had also taken all of the plants, except vals, out and misted them with excel.
