    Pump Questions

    Man I am getting a bald patch in the front of my tank!

    I have a Mag 12 (sump return 100 GPH or so) and a Quiet one 6000 (closed loop 1500 GPH or so) feeding open bulkeads at the back of the tank. Where the flows colide @ the front and center of the tank, my fine, fine argonite sand is being blown back! I have about a foot of bare tank bottom and it looks ugly.

    With these pumps, can I set them on a timer to alternate? Say every 30 seconds or so?I'd get a bit of a wave pattern and avoid the costant flow collision.

    I've read that the mags lifespan can be shortened by this, anyone try it before?

    Thanks!

    From my understanding, having your pumps turn on and off constantly is very hard on the pump. I personally wouldn't do it to my pumps. You could always use a wavemaking device or actuated ball valves...

    Isn't that exactly what a wavemaking device does? Turns the pumps off and on?

    A quick google on the ball valves you mentioned leads me to believe these are valves that open or shut based on either air pressure or electricity? Has anyone ever used these for this application? Are they expensive to buy/install?

    Thanks for the response

    I think that wavemakers are hard on powerheads. Either that or powerheads have a "soft start" feature installed in them.

    Actuated ballvalves are about $300 each, so I don't think you want to go that route....it would be pretty sweet if ya did though!

    YES electronic wave makers are hard on power heads unless the power head can handle the sudden and frequent on and off cycles that are created. Most wave makers will include with their manual a list of suitable, tested power heads that can be used.

    I saw a thing once on a webpage, it didn't shut off the powerhead, but was an attachment that totally redirected it every few seconds, in short bursts. Rather then the more common other attachments where it moves it slowly. The goal was to save powerheads. i remember there was other attachments that were to attach to various other types of pumps and outputs not just powerheads.

    To clarify, I'm talking about a couple of specific pumps... not powerheads.

    thanks!

    The Mag's should not be used with a wave maker, it will significantly shorten their lives the only pumps i have really seen handle it well are the maxijets
