    Water Flow

    Currently I have 3 Maxi-Jet 1200 Power Heads 295 gph and a Fluval 404 340 gph with spraybar on my 72g. I have a spare 402 270 gph powerhead and was thinking I could take the Fluval off and install the 402 instead. Flow with the Fluval and powerheads is 1225 gph and with all 4 powerheads its 1155 gph. Which setup would be the best?

    Thanks
    James

    if you're using the fluval just for the flow, i would stick with the powerhead instead. much easier to maintain and one less thing that can leak/cause problems/etc.

    I'd add the powerhead and keep the cannister. Maybe put one or two powerheads on timers to mix up the flow a little.
    Contrary to popular belief, a cannister filter won't raise your nitrates- especially if you keep it clean. And it gives you the option of doing some chemical filtration, like carbon or phosphate removers or poly filter when the need arises...

    Yeah I am worried abit about the Fluval leaking, the connections arent all that solid and I dont like the idea of having to clean it out every so often plus intake and outtake look bad in the tank. For a timer, Im using a Aquarium Systems Natural Wave Multi-Cycle Pump Timer for 3 of the powerheads. How many heads would I point towards the surface of the water for air exchange if I were to use only powerheads? Right now I have the Fluval spraybar flowing across the suface.

    you can aim two at the surface and set it on the timer so there is always one pointing at the surface and one regular.
