Ok The trickle filter is a homemade one we got the idea for from a set of plans we found online. The plans consisted of a 5 gal bucket, plastic sponges, egg crate, filter media, and filter media. We just made it smaller by using a 4in pipe in stead of a 5 gal bucket. I take pictures of it taken apart post them as soon as I can. The protein skimmers are BioPro air driven protein skimmers rated for 60 gal. both tanks all together are 75 gal. i placed the pump on a stand to keep it from over flowing the top tank. can't I do that or does it have to be on the bottem of the tank?
And what kind of pump do I need: A pond pump or a sump pump?
