How many U-tubes can one Aqualifter pump keep bubble-free?

I have a tank system that consists of 4 tanks total (a 25g, 20g, 5.5 fuge, and 4g sump/skimmer).

All of the tanks are even along the top (stand built to hold this sort of arrangement).

They are all connected with one U-tube in between each tank. Water flows from the left tank directly to the far right tank/sump... and back through them all to the left tank (one MJ 1200)

Anyhow, the U-tubes do not have enough water flow to remove the bubbles. I cannot generate enough water flow to remove the bubbles without overflowing the first tank in the system b/c there is not enough gravity pull for a high flow. It must be a gentle flow.


This has worked well for two months but I would really like to remove the bubbles.

If I used airline tubing "T" connectors to converge them all into one pump, could I connect all four of these to a single Aqualifter pump to remove the bubbles? It takes a week for any of the tubes to generate much air, so we're not talking a whole lot.

 

It's a coin toss. Don't know anyone who has done it. It could work and might. My only worry is the difference in resistances between the hoses. Lets say one hose removes the bubbles first, will the others continue to remove bubbles, or just keep pumping water from that one?????

I say try it, and post your results.


EDIT:

And we need pics. Sounds like a neat setup.

 

No pics available yet, but I'll get some soon.

The system is actually quite simple. The tank on the far left pumps over to the sump tank on the far right. The water flows into the fuge (via a U tube), into the 20g via another U tube, and back into the first tank, the 25 via a U tube.



You bring up the resistance issue, which is the only real thing that concerns me. I think that the tubes with air in them will empty first, since (I suspect) there will be less resistance.

We will see. I'm going to try to do this without tapping into the top of the U-tubes. I'm going to try to run rigid tubing up into the U-tube and use some thick superglue to temporarily hold them in place to try this out. If it works, I'll fasten them with marine epoxy or some Weld-On 4. I may even use the oven burner to heat bend them to conform the bend of the tube.

 

if you use power heads for flow in the system you should be able to use the air hose attachment on the power heads that makes bubbles to suck the air out of your u tubes i seen a setup on the garf site doing this
