I asked in another forum and wasn't getting anywhere so I thought I would try here....

I bought a used setup from a buddy. He has the drain line hard plumbed in 1" pvc. It is a dual overflow system... At the sump I have an annoying amount of gurgling and dissolving bubbles. Any ideas on ridding myself of such problems? thanks in advance

Do you have Durso type plumbing inside the overflow itself?

BTW, you a Crew Chief?

Yes they are durso pipes, and no I am just a backshop engine troop on the B1B

Two suggestions for you:

1) Look here. Marc has some great ideas. http://www.melevsreef.com/

2) I have two overflows from my tank to my sump. On one of them, I use this type of hose. I don't know how well you can see it, but it has ripples along the inside and outside. This seems to break up the bubbles and it is much quieter than strait PVC pipe.

Is it an air problem or just rushing water that the flex line fixes? I don't have any noise until the water hits the sump. This is when i get the eruption of noise/air/bubbles! I am just inexperienced at this whole bit and the noise is driving my wife crazy...

Does the pvc go into the water in the sump, or is it just above? if it is not in the water, you might add a short piece of pvc, or a piece of "flex hose" to get it below water level in your sump, this may help.... You will still have some gurgling, but should not be as bad...

Tell your wife it is a part of oxygenating the water. LOL

I also have mine plumbed with 1" solid PVC and have the same problem. Mine is not very loud but I can hear it. I think its because I ran my PVC horizontal from the overflow to the intake section and refug section of the sump. I think I read on Melevs Reef (http://www.melevsreef.com) that you should run them at a slight angle to avoid this but of course I forgot this when setting it up.

Oh well, its in the kitchen and noise isnt an issue. Usually the smoke alarm going off while dinner is being made is a bigger issue. :lol: :lol:

I don't have 2 overflows but had a lot of noise due to my return pump being way to strong. Put a ball valve with a tee and turned the pump down. Now I can't hear the water flowing with the lights on. Now I just need to get quieter fans.

This seems to work well for me:
Get a length of PVC so that it is long enough to fully submerge in your sump. Putting it at a 45 degree angle helps a little. Now drill a bunch of holes in it so some are above and some below the water line. If one doesn't do it, they adding a T and using (2).

Another approach I use, depending on the tank is to put a 90 or (2) 45s on the drain line so that the water enters the sump parallel to the water line, just below the water. I typically use this in tanks where I plan to grow cheato, as this gives them water current to tumble.

Both work, it just depends on your sump. I use a combo of them both on my current tank. The idea is to get the air out of the water without mixing or splashing. When your plumbing ages, the problem goes away some as well.

Hope that helps.
