over flow
over flow
I will be curious to see what responce you get.
I have one tank running 2 u tubes and worry a little.
I can say I don't have air build up any more after I went with a big pump, I'm running 2 u tubes at all they can flow.
before I had 1 with a smaller pump . air would build up in the top of the u. as soon as the flow went up all the air is flushed out.
I wish this tank was drilled in the bottom.
I have seen the flat tubes collect air and lose their siphon.
In my opinion any siphon tube running low flow is prone to stopping. I think they sell some kind of device that keeps the air out.

Hey how does the aqualifter work ?

Slave to the reef!
its basically a small pump that sucks water in and pushes it out with a diaphram simialr to an airpump but with water.
Basically you would need to drill a small hole in the u-tube and install a 1/8" male fitting. The pump would then suck air/water fromt he overflow and return into the tank or sump.
Not sure where to get the right fitting though. But im sure it would work and save you a good chunk of change.

I have found the trick is having enough flow going thru the U tube to keep the bubbles from building up in the first place.
I know thats not always an option but when I was running about 300gph thru the overflow bubble would slowly build up but after switching to a larger pumprated at 800gph the water would travel so fast thru the U-tube that it would pull any bubbles thru also.

Then a smaller U tube will also speed up the flow thru it.

One u-tube can't handle the flow 2 is to much. I can crank the flow up way higher than the u-tubes can even handle. What is the max flow that 1 u-tube can handle. I'm only running about 600gph now through my sump i really don't want to drop it any lower.
The CPR would be okay but make sure you get the aqualifter. They should just sell them packaged together.

personally i would not be too fond of drilling a hole in a u-tube. I would rather run some air hose to the apex of the u-tube, that would be connected to a pump/aqualifter.
it is kinda funny, cause i have been thinking about this very issue lately, and was thinking about going with one of those CPR's with aqualifter pumps. Mostly because i want the lower profile.

Yeah, I am not too fond of drilling into the U-tube either at this point. I enjoy experimenting with things like that, but not without a backup.
I think I am going to try a larger return pump first and dial back any excessive flow that the u-tube can't handle. I don't quite know what the return flow is currently, but I would like a bit faster turnover.
If that doesn't work, I'll start playing with the u-tube or a CPR. I would like to have a backup pump anyway.
So what would be a good return pump and how much gph do you think the U-tube can handle? My current pump is submersible, should I consider an external?

u tube
u tube
I have a 75 gallon with a mag 7 untill I ran 1" pvc ,the over flow box ran just fine, as soon as I ran the 1" the purchased box would not keep up with the flow. I had to put a valve and slightly
choke it back.
you did not say what size line you have from the pump but it does not take much of a restriction to reduce the flow rate
