got an idea of doing 4 units of 60 gallon tank and doing a rack on them all together or two seperate double deck. can i use a single 400 gal capacity wet/dry filter for 4 tanks?
cutting cost on electric and cut the whole octopus type wires that will be all around if i use individual filters for each.
