    So, almost finished with the closed loop plumbing on my 135. Now, I wanted to add some flow accelerators to the tank. I was looking at the eductor/penductor type and was wondering who has used flow accelerators and if they can tell me if there is any difference in what to buy. I was thinking of going with these from champion lighting and supply:

    But I also saw these at marine depot and was wondering what the difference was, is there a difference and which is recommended:

    Any help would be appreciated!

    I have the ones from champion and they made a big difference. I'm very happy with them

    Thanks Matt. By the way, I dropped the hole saws off this morning. I put them on the mail box next to the door. Thanks!

    I used to use something like the first pic. I liked them. But when i integrated an ocean motions valve into the return, the back pressure from the flow accelerators messed with the pressures on the ocean motion valve and the valve didn't work very well.

    That's good to know cause I was planning on using them on my 2 ocean motions when I set up my next tank. Andy what size flow accelerators and oceans motions were you using?

    Hmmm. So, I have a dart reeflo pump and a 4-way ocean motion that I was going to be using.

    I have 2 drains that are 1.5 in diameter feeding into the pump. Then the ocean motion feeds 4 inlets that are 1 in diameter. I was planning on running the flow accelerators on all the 1in inlets. Is this not going to work? ...

    Pete if your bulk heads are 1" npt we could remove my flow accelerators for a few hours and test them with your oceans motion and see how they work before you invest money on new ones. Would have to be on a Mon or tues night though

    Matt, that would be awesome. I have a few touches to do on the plumbing and then I got to fill it with water. Hoping to do that this weekend. A Monday or Tuesday would be fine.

    While they do accelerate the flow, I believe they also cut way back on the total gallons per hour. That may not be a concern to you, but keep it in mind.

    I had several things going against me with the OM and the eductors.
    1st the OM was plumbed off a manifold. Not a dedicated pump; which it should be.
    The pump had too much pressure for the OM with the eductors. The OM would fail, the magnet would silp. The drum could not cut the high pressure water current through the 4way valve.
    leaving the eductors i throttled back the OM manifold circuit, and the eductor back pressures still created nothing but headaches. As the OM cycled, the pressurees would dramatically rise and fall as it changed between the four OM channels.
    The eductors created too much back pressure. When the eductors were removed i did not have the pressure issues with the OM, and and the OM worked fine.
    As i look back, my OM magdrive gears failed , i attriubute the eductors to that failure.

    My experience tells me that the OM needs to have a dedicated pump without anything adding a lot of back pressure. If there is too much back pressure the OM drum can not pass through the water current easily.

    I think OM used to have a FAQ or forum section on their website where they responded that they do not suggest the use of the eductors with their products.
