![]() Hi everyone!
I'm a newbie to this whole reef/saltwater obsession and had a few questions. If you could answer them or give me a link to some good info I'd greatly appreciate it. 1) What is a sump? What is the purpose of a sump? 2) What is an overflow? What is the purpose? 3) What does closed loop mean? Thanks!
