Hi I'm new to the forum and new to the hobby. I had fresh water tanks growing up but just got my first saltwater this summer used. I have a 29 gal fresh at home with a 75 gal saltwater with 20 gal refugium at home. Then at the shop a 29 gal fresh, 90 gal saltwater planning another 20 gal refugium on it also, a 55 gal saltwater, and a 20 quarantine tank. I still have my 10 gal tank that started this.... lol
