    how much flow do I need?

    my tank is 75 gallons with 40 lbs reef bones and 20 lbs live rock (so far)

    I have a jet nozzle on my renaxp3 (350 gph I believe) and an aquaclear,I think a 40 at 200gph and an internal uv sterilizer at 80 gph,don`t think the sterilizer moves a lot of water.

    Is this enough or should I add a seio pump? they seem to look less ugly in tank or are there other unobtrusive pumps? hate the clutter!

    what about the zoomed rotating pumps?

    You should add one or more of these once they come out:

    They should be available March-May timeframe.

    Unfortunately, they will likely be almost the price of a DC Tunze Stream.

    You should aim for more like 10X turnover at a minimum (you are currently at 8.4X) with 15-20 X being better. Some SPS dedicated tanks are running 40-100 X turnover.

    Stream type powerheads are wonderful for extra flow and Seios are the cheaper option. The ZooMed rotating pumps are great but seem to jam and fail after only a few weeks of operation.

    Hi Gerry,

    That's not enough flow. A rule of thumb is that you want your tank to turn over a minimum of 10x it's volume. With your tank being a 75 gallon, that means 750gph.

    I'd add a couple maxijet 1200's, and if it's in your budget, go for a wavemaker to alternate the current randomly.

    The wavemaker is not entirely necessary if you don't plan on having corals though.

    The Zoomed pumps look good on paper, but don't fair well in a saltwater environment as they get jammed up pretty quickly.
