This is the Japanese motored version of Iwaki's 960gph pump. They generally run about $225 new, and are more durable than their cheaper US-made cousins. This pump ran as my closed loop for awhile, but has sat since I reconfigured my tank. Still runs silent and is in good working order. $100. I'd consider trades trades or partial trades for frags, Apex Aquacontroller modules, an in-sump skimmer appropriate for a 42 gallon tank, welding supplies (especially an inert gas regulator or flowmeter), argon tank, or '66-'77 Bronco parts.
