4 currently:
2 on one system
2 small qt/hospital tanks.
About to set up another 2 tank system
Also, periodically, 1 or more small tanks for raising babies.
Clean glass daily when feeding(so it doesn't build up)
Water change big tanks one weekend all small tanks following weekend.
I can do a water change and clean skimmer in about 10-15 minutes.
(of course baby tanks have to be done daily, but not much water involved)
