I have a freind who is selling a combo wet dry and skimmer. It is a proclear aquatics and has the pump for the skimmer and a return pump that would work great for your tank. He wants about $120.00 for it and shipping will be about $25.00. I had the same system and it works great. Skimmer is before bioballs. New price is about $300.00. The only thing you would need is an overflow and they are about $35.00. Please PM me if your interested.
