Thanks. I will set my pps pro dosing more than i had it set. I will be leaving my co2 24/7. Im guessing my ph is more than 8 (im out of ph test) that my co2 is low and the eco is buffering up my ph. Im putting 3x dose excell right now to see if that helps on some diff algae thats growing right now. The culpit off all this is low co2 from the eco buffering my ph up. I set my co2 10bps or more this morning and my drop checker didnt change till this afternoon to yellow. Thanks alot for ur help.
