Bubbles In Overflow Line!!

Just set up my refugium and all seems well but.... the water coming from the overflow( 1-1/4" bulkhead 1" line) comes into my refugium and is causing more than a few bubbles. I tried a smaller(3/4" ) overflow line but it just made more noise and didn't help the bubble issue. Anyone have any ideas?
I will try and take some pics or vid tomorrow.

Thanks in advance for all your help,
Trey

 

If you have the room install a bubble trap

 

I have a bubble trap but the velocity of the water coming from the overflow is to fast, so it creating lots of fine bubbles. Somehow I need to slow the flow into my bio-balls.

 

i had a similar issue when i set up my fuge. i am running an eshopps overfow that i am not super impressed with but it delivers the water i need. i ditched the initial box that goes into my tank and let the u-tube pull directly from my tank. what this did was fill the box on the back of the tank eliminating noise and keeping bubbles out of my fuge. this will also allow more flow so i reccomend the use of a ball valve(relly cheap and easy ACE hardware).
good luck hope this helps.

 

You could use a filter sock at the end of the line in the refuge. You have to keep them clean though. You can also build a bubble trap in your refuge as stated in the previous post. All you need is 3 pieces of acrylic sheets.

 

Had that prob too i made a spray bar to difuse the incoming water

 

I had the same problem. I extended the tube, so the incoming water comes into deeper water and takes care of some of the turbulance and bubbles.

 

i saw a cheap and easy way to reduce/trap micro bubbles and excess noise from water entering the sump. just zip tie a standard sock (yes, for your feet) onto the pipe/tube/pvc. make sure it's clean and has never been exposed to detergent or bleach...good to go.

 

How much water do you have going into your fuge? If I am reading it correctly, yo have a 30 gal tank and you have a 1" line from you tank dumping into the fuge??? What size it it?

In my book a fuge should only turn over 1x hour.
