sump info
I bought it from the local aquarium shop owner. He has had it running for a year or so. I will get it Monday. Suppose I'll keep the biomass wet and clean out the rest so as to keep some bacteria in the system as his fish will go straight back in the tank with the sand and as much old water as I can keep which won't be much at all. Sump is 3 chamber. 1st has wool, 2Nd has biomass and 3 the return pump. 6 foot tank 4 foot sump
