Might have a 20g Nuvo peninsula, upgrade return to mighty jet, ghost skimmer (lost the lid), stand, AI sol with hanging kit. Could throw in some new rock too. $140
I have a complete up and running 20 gal tall system Ive been thinking about selling. Has bonded percula clowns & nem, other easy corals, 20 lb live rock and a couple gobys. Tank, stand, 10 gal homemade sump/fuge, hydor return pump, heaters, tunze ATO, ai prime, 2 powerheads. Probably a few other pieces of equipment I'm forgetting. Most equipment is 1-2 years old. I would estimate I have about $700 into it. I'd sell it all for $500, or make me an offer. I can send pics if you are interested
