I am looking to add a frag tank and quarantine tank. I am buying a 40g breeder and stand from Craigslist for $100. I would like to add a sump to it so will be looking for another tank and overflow box (right now I don’t plan to drill the tank). Also, light, live rock, return pump, circulation pumps, frag stand.
For the quarantine tank I will probably go with a 10g with HOB filter. I have a 10g tank.
Any suggestions?
