I imagine you have done pretend power outage to see what would happen.

Acctually, we have a outage atleast once a month. AND, I shut my pump off completely every water change.

My closed loop intake is at the bottom of the overflow. And the drain into the sump is a Durso style. There is No reason why you cant have a Closed loop intake in an overflow

Pentair Quiet one 3000 for my closed loop, and a MAG 3.5 for my sump return.

Why would it make a difference what pump I used? they have an intake and outlet, which you attach pipes to

i had mr albertas old cube.
i had the closed loop in take in the overflow(coast to coast).mag 24
and a durso intake for the sump.mag 18 return
when the power went out water only went down to the durso level.
the closed loop had no effect on the level in the sump.

typically a closed loop is used to get flow into the tank without power heads, if you used a large pump on your closed loop there simply isn't enough water going through the teeth on the overflow box to keep the pump functioning, you might be getting away with this with a medium sized pump, but to recommend this to the average reefer is asking for trouble.

Dursos will control the height of the overflow box but returns from the sump into the tank will also cause back flow, as can be seen from Des pic his system will fail, as will any other
system that isnt don exactly correctly, why ask for trouble.

not only that, the correct way to use a feed to a closed loop pump is the get the goodness out of the rock and into the water column, you use the pump feed to enhance movement in the tank, doing this from the overflow box means you are losing the flow you could have used to your advantage, your teeth in the overflow box need to be low enough for the CL to get enough water, if this is the case then you are not surface skimming which is the whole point of the overflow box.

I didn't say your system wouldn't work, your closed loop pump is 700 gph, the teeth can handle that quantity, you cannot do this with a 3000gph pump it simply will drain overflow box.

Dez, have you considered a strainer used on jetted tubs or hot tubs, would stick into the tank 1/4" or less.

Finally, someone on topic. Do you have pics of any. That might be a good option. I spoke to someone recently after posting this thread who has a lot of experience and I'll probably go with his idea. However, I would still need a strainer or eggcrate, any link? Thanks Mark.
