tank questions

[zum14]

check out www.monsterfishkeepers.com they have tonnes of guys running sumps on there. Basically it is like everyone is saying, it turns it to one large filter. Ive seen lots of guys run basically sink "scubbies" as there cheap and kind of a bio ball. Guys usually do the same as salt, run your heater, carbon, any phosphate removers. Cleans up the main tank.
