Re: gas exchange

no sump as of yet..i've been reading  a lot lately about overflows and sumps
and I'm getting VERY interested in setting one up for myself...all i've got
right now is just the tank..water stays inside the 4 walls of glass, i'm
thinking of having a 33g tank and a 33g underneath modified to be a
sump..too bad I don't have the cash for that... :/
