Help with micro-bubbles please

[Masterderrull]

I just finished setting up my 90 gal display that has "bean animals" three drain overflow running to my fuge which is ten feet below the water line. The siphon line has no bubbles coming out of it. The open channel standpipe is tuned just right, I'm niether gaining water or losing it, but I have so many micro-bubbles that they're making it past my bubble trap through a polyester filter pad and back into the display. the drain lines all end in the sump water about 1-2" deep with a tee on the end. If anybody has advise on how to correct this that would be great.
Thanks

You probably thought of this already, but are you sure the micro-bubbles escaping into your display are created by the drain pipe splashing and not by your skimmer?

yes, the skimmer is in a seperate rubermaid. The drain line from the rubermaid (skimmer) is gravity fed into the fuge, this drain line has almost no bubbles at all. The bubbles that are present from the rubermaid are two big and easliy surface.

If you have room try a 90 on each end of the T pointing away from your bubble trap. This will push all your bubbles away from trap and hopefully dissipate them enough the bubble trap will stop them. You also may have to slow down or divert your return. If you slow the water down flowing through the sump the bubbles won't have the velocity to carry thru bubble trap. Oh and a filter sock might help also.

What is the set up your current bubble trap? Is it as far away from the return pump as possible?

Just a thought, but shouldn't the open channel line be draining into the skimmer container to feed the skimmer with the most nutrient-laden water available? Doing this, if possible, is one way you could take care of the problem.

I took your guys advice and tried messing around with it a little bit. I dont want to replumb it to the skimmer unless I have to. Right now it seems to be better than before. I did angle some 90's up in the air, aculatly there sticking out of the water completely and seems to have helped tremendously (sp). There is still some mb's but it seems a little more reasonable now. Hopefully things clear up here soon. I'll keep you updated.

Another thing that might be a possibility is air bubbles trapped in your return pump.

Before I got my ATO, when the water level dropped below the grating on my eheim pump some bubbles would get trapped. The pump was shooting MB for weeks! I finally drilled a few small holes in the slits so bubbles can rise through them.

Just throwing ideas.

Ok so the bubbles are gone. Everything is working perfectly, except for the little giant pump that i bought off of somebody to run my om4, I was told it was brand new. It's not after runnig a 220v elec. line plumbing everything in and getting all excited it's as loud at a train. I found out that some bushing on the shaft are broke and that nobody carries replacement parts because they quit making the pump in 2002. Oh well there goes $100.

By the way, to the people I bought stuff off of: the skimmer works great, the OM4 works fine from what I can tell, and my reeflo black fin is a beast, thanks everybody.

Now all I need is some cheato, rubble rock, live sand, a home depot light, filter socks, and a few other things I'm buying from people. Anybody out there got some extras??
