* to accomplish this with a closed loop you would need 2 pumps and really good timers and ball valves on your output piping to control amount of flow. You would also need reliable check valves.

What is your closed loop hole placement in your tank?

Hi Kevin,



There are 4 holes drilled in the top brace to accommodate 4 seaswirls, which were to be fed by the 4 holes drilled in the lower bottom back of the tank.
My original sump return was to be determined and because the tank is acrylic I have the ability to reasonable modify it.

What I would like to do is use only the front two top holes for the seaswirls and drop a couple supply pipes originating from the sump down the back two top holes.
The two supply pipes would alternate the flow, clockwise or counter clockwise in 5 hours one direction with a 1 hour rest followed by 5 hours in the opposite direction, 1 hour rest. Repeat.
The top zone would be kept moving through the closed loop full time.
I have 1 reeflo dart supergold for the closed loop and 1 reeflo dart supergold for the sump return.

Depending on the results of the final setup, I was leaving open the option of adding the MP60's. The price of them is giving me a lot of incentive to minimize how many (if any) I put in there.

It sounds like there is a design that would work from Oceans Motions, but since there are other suggestions coming up in this vendor forum I should probably continue this on my build thread.
I really appreciate everybody's suggestions so far!

Another issue I thought of is that as well as having the OM unit work, the pump supplying the OM unit would need to be synced to turn off and on at the correct time.

If you simply want the water to flow from left to right every 5 hours,then I can show you how to do this without an OM unit, do you plan on leaving the pump off for a one hour period or do you want the water to go elsewhere during that period?

Hi Paul,
I was originally looking to incorporate the switching and rest setup with a single sump return. The pump would be off during that rest period.
The 5/1/5 setup was to replicate natural ocean currents in the main tank.
I don't have anywhere else for the water to go....yet ..
