so i just recently got an offer to trade my 125 for a 330g and the big problem is that i do not know how to set up a sump filter and how it functions. can someone explain how much it will cost me to buy a return pump or whatever pumps i need to set this up.
the dude has all the plumbing and bioballs but he says i need a pump idk really how much that will cost and how it functions.
any help is apriciated here is the sump and the tank

can you guys also help me with refugiums because i currently have a 10g growout tank could i incorporate those fish in with the sump or no?
