Yeah, I know, if you read back on my thread I really haven't established an underlying cause yet, I lowered the power of my lights quite a bit, my flow's good, I dose ferts including nitrates, and so on... I tried hydrogen peroxide and it seems to have worked really well so far, fingers crossed that when my CO2 gets hooked up today it'll be enough to keep it gone for good!
Also yeah my CO2 cylinder came today! Early Christmas present to myself!
