yes, my idea (not really my idea) was to use a ocean clear canister filter hooked up a high flow pump I got for a deal off of Reefrontiers with an inline heater. Although I am really happy with the Hydor inline heaters, I might use the Lifegard modules too b/c of the fact that the inlets/outlets do of the Hydors are smaller than the 3/4 inch pipe I am thinking to plumb with. This way lots of flow. That you have four holes is probably ideal, I was only going to do two holes as it will be a glass tank which makes me nervous drilled. If I were you I would definitely consider the closed loop filtration, you could hook it up to a powerful canister as well if you didnt want to use a pump. I am really excited about the idea of no cables/spraybars in the tank. One guy I talked to with a similar system, but a reducer that he could hook his CO2 into before the filter and the filter broke up the co2 great without needing a reactor or diffuser. sounds good to me Kypros On Mon, Dec 7, 2009 at 2:51 PM, Jeff <jeff@gotperk.com> wrote: > Very interesting Kypros, my new tank was a saltwater tank originally and > the > guy has four 1.5" holes drilled at the bottom (two at each end) for the > high > recirculating flow you are referring to; this is in addition to two corner > overflows for the wet/dry; I was going to just plug these for my fw planted > tank layout but now I will consider utilizing them for a continuous > recirculation pump with maybe a couple inline heater modules from Livegard; > Thanks for the idea!
