    Pump for Sump

    I just started using a Mag 24 for my sump return and I absolutly hate it it's extremly loud, even when suspended in the water so it's not viberation. So my question is does anyone know how to make it quieter of know of another
    pump (1500-2400gph) that is quieter.

    Thanks for your help

    Ehiem is the only pump I'd buy.

    wow - I've had only good luck with the mags as far as being quite. I moved from the mag 7 to an external Iwaki pump and while I like it as far as power, aesthetics, and starting reliability, it is noisy as you know what.. not that it helps ya much, but if quite is what your after, I'd stay away from the external Iwaki's. That said, I'd totally buy one again if I had to because my sump is in the garage so I don't have to worry about noise.

    I can't beleive your having loudness trouble even after suspending it in water. That doesn't seem to make much sense unless it's rubbing against something else to create the strong vibration noise. hmmm.. well good luck

    Eheims are also great pumps - ditto to Don's recomendations. All around I just love 'em, but they are expensive. I guess like most things in life, you get what you pay for.

    Is the pump plumbed with rigid or flexible tubing? Sometimes switching to spaflex (from rigid PVC) will make a huge difference.

    Class clown - I agree with you the iwakis are great pumps I went from an external iwaki to the in sump Mag, due the the noise of the iwaki

    Dnjan - it's a combination of both rigid and Spa flex

    You might need a longer section of flex. I used too short a piece of flex on my skimmer pump, and it can be louder than my return pump.

    Also, watch for the rigid touching the wall of your stand (or even the wall of your sump). Amazing how a thin, flat object will resonate!

    I shoved my mag 24 in the closet within a week of use because it is SO loud. I really like my mag 18. It is not any louder than the sedra 5000 on my skimmer.

    Not yet but they are comming out with a 1265 already out in europe. Even with the less flow I'd still go with the eheim especially for a return pump. Even if I had a huge 500 + g system that needed that much flow through the sump I'd go with 2 eheim's over a mag any day.

    pumps ive tried for my return, dislikes / likes and where they ended up.
    All in just over two years of wasting money

    Mag 24 / very loud / stalled / Gave away
    Mag 9 / very loud / use to mix salt
    Iwaki 30 / very loud / Collecting dust
    Iwaki 40 / very loud / Trash
    pcx 40 / very loud / stalled / gave away
    genx 8000?/ very loud / stalled / Trash
    Amp master 2500 / leaked / collecting dust
    Quiet One 4000 / stalled / trash
    Quiet One 5000 / Loud / stalled / gave away
    Eheim 1260 / silent / moved to chiller
    Eheim 1262 / silent / still running

    The ehiem sounds pretty good for a return pump. ive got a 600 gph over flow, do you think the 1260 would be good enough or would I need the 1262?

    Ive seen the DIY projects you've done and every time I log in I get more respect for what you know. Its posts like these that make a person realize why everyone around this site takes so much stock in what you say. I will keep this list in mind when my return pump goes out.

    I'm happy if I can turn my sump 10 times a hour. I could easily flow a few thousand gph but its just not needed IMO. I dont concider the return as part of flow.

    so if I have a 30gal sump on my 75gal tank w/ 600gph return, your saying all I really need is a return pump that does at least 300gph?

    IMO that would work fine. But I would have somewhere around 7500 gph in closed loop in a 75 if it were mine.
