Oceansmotions

[Holyreefer]

Those of you who own oceanmotions... Does anyone have theres on there main pump returning from the sump?

[zach0660]

I think thats how most people set them up.

your sump pump should only be 3-5x your display tank's volume per hour. I can't see why anyone would have theirs plumbed off such a low volume per hour. I would imagine 95% of OceanMotion users are using theirs off their closed loops pump.

[aiko670]

Nope, too much flow through the sump...

[MplsMan]

i was thinking on doing that for my 110, i would have about 800-1000 gallong going through it.

oct2274...
for figuring the turnover rate for a 110 how do you figure that out ?
thanks

[oct2274]

return pump for 110 = 110 x 5 = 550gph after headloss

you will get your additional turnover for your corals from a closed loops system which commonly uses an OceansMotion or you can used power heads like the koralias, tunzes, or other.

I have the 8 way on a cl using a dart pump.Unless your plumbing is up high you would siphon out the water in your tank if there is a power outage.That or your sump and tank are at the same level.You can probably do it with a back water vale.Power goes off it won't siphon the tank.Like this onetp://oceanaquatics.com/store/product/301/True-Union-Check-Valve-1.5%22/

[Holyreefer]

Well, i have been thinking about adding it to the main return and having it over my tank with a check value so it doesn't siphon out my tank but i believe this is what i am going to do so i don't have to have all types of pumps everywhere.

Its already going to be enough for me to have the Closed loop pump, my skimmer pump, calcuim reactor, phophate reactor plumbing as well.

I'm going to t off for my chiller off of the main sump which will be a stock tank, also with my chiller, and my refigum...

Continue with the replies thanks

so i'm guessing from you figures that i would need at least 550 gph turnover for my 110?

i called coralife and they caculated i would have 840-900 gph at 9'
thanks for the help.

What is the rationale for the 3-5x number?

I have a Mag 950 on my sump, and my tank is only a 46 gallon. The sump is a 15 tall glass fish tank.

[LobsterOfJustice]

I've always thought 3-5x is a little low. Seems like that's not even enough flow to keep the main tank up to temperature if you have a heater in your sump. I usually go for about 10x through the sump, but it all depends on the size of the tank, size of the sump, and size of the pump on your skimmer.

That said, most people use them on closed loops, but there is no reason you can not use it on a return.

[ShapeGSX]

5x wouldn't even be enough flow to keep bubbles out of the U tube on my hang on back overflow.

[nauticac4]

I am running mine through a Dart (3600gph) throught 2-1.5" bulkheads in a closed loop. I have split the 4 way into 8 outputs (2 on eash of the 4 way outputs). I run an Eheim 1626 as a return pump from the sump, it is a split return to the fuge and the display and throttled back considerably with a gate valve.

[zuzecawi]

I wouldn't trust my floor to a check valve, but that's just me. I run my OM's on closed loops.

[sheaD]

"I run an Eheim 1626 as a return pump from the sump"...........That would be an Eheim 1262.

[sheaD]

Run the oceansmotions as a closed loop. If you get a pump with the balls to do it you can run a siphon feed over the back of your tank. Most people just have their tank drilled though.

Never rely on a check valve to prevent back-siphoning. It WILL eventually fail. Even before it fails completely it will leak so that given enough time it will back-siphon as if there were no check valve. Instead put small holes in the return lines just below the water surface. When the water level drops they will suck air and break the siphon.

[Holyreefer]

or couldn't i just keep the return lines from the sump above the drain lines in my tank that way it won't siphon?

[ShapeGSX]

You could. But you will end up with a ton of splashing. Even if it doesn't look like it, there will be water in the air.
