Yeah, I'm not sure what happened. the only thing I can think of is that I didn't add the two airstones on the end until 4 days after I put them in the new res, so maybe it was just too long? The picture makes it look worse than it is I think. I should have taken an underside shot of the right side because its probably about 60% white roots and black on the inside. Do you think I need even more air stones? I have three bubble curtains and two 10" stones in there right now.

I will start adding the H2O2 regularly. Is 2.5 gallons enough water to dilute it?
