good to hear. maracyn does work very well, but i would still make sure your nitrate is above 0.

i nuked mine in 2 days by swirling a toothbrush around to collect what i could and a b/o. worked well for me.

I've got that too, so I'm going to try to black out for 4 days. I need a stronger filter with more flow..........I think that's my problem.
