I just picked up a 75 Gallon tank with stand, Viparspectra light, sump, return pump, Berlin protein skimmer, magnetic powerhead, two wave makers, heater, some smaller accessories and over 100 lbs of live rock for $200! I'm new to having a sump so here's my question. The gentleman I bought it off of said to put some live rock in the boxed area of the sump and the protein skimmer on the other side. This is all I do? I've been reading that this is a great way for filtration but I want to make sure that I'm getting opinions as well. I'm coming from a 40 gallon with a skimmer and canister filter to something I've not dealt with. I asked him about bio balls and he said hell no! That's old school...lol! Any opinion is appreciated.
