    I recently tested my tanks P levels (I follow EI) and I found that I had a value somewhere close to 10ppm. However I still get some GSA on my anubias leaves and glass. Granted it has gotten a bit better over time, but never completely go away. I also have minute amounts of BBA. Very minute and it doesnt really spread. I used to add 2ppm of P 4 x a week ( a gross excess) but have stopped adding them while performing my regular water changes to get hte levels down. I will dose a bit more like 2ppm weekly. Howver my question is, is this a co2 issue?? I keep my co2 levels over 30ppm at all times but thought maybe as a result of variations in my ph and kh tests it could be dipping below that and cause the GSA. any thoughts??

    Add more CO2 slowly.

    BBA and GSA both scream low CO2.
    PO4 is high, you surely don't need that much, reduce dosing to 2-3ppm per week and do the weekly water changes etc(It'll never exceed 4ppm then).
