No actually, it is an aquarium ecosystems sump that I traded some video games for. Pretty nice guy, he gave me an aqua c pro and overflows with it, as well as the return pump. The behind the tank idea shouldnt be long term, it is a real pain in the @&#, if you know what I mean, very hard to reach, but you dont really need much access once it is set up with ato, I automate wc's too, I just w8 for the topoff to empy, then put 5 gallons in there, then drain five from my display slowely, I only have a 65 gph pump.
