ive recently been to a fish farm and im wondering, can u use the tanks the use for like koi? the tank would be made up of concrete with a sealer, with a pannel of glass for looking.
if this is ok... we saltwater fans could greatly expant our tank size, with no extracost.
p.s. how many of us paint the back of the tank black?
