Excellent!

Thanks Zandor....

I think I've got my problem... everything is new... so, I think the culprit is the air stone. I bought the cheap $1.20 one.... I should have bought the $7 one.

Anyway, I'll buy one of the costly ones and see how it fares against the one I have.... If it does substantially better, then I'll buy 2 or 3 more.

Thanks Zandor!
