Bubble problem with hang on fuge

lcs · 04/27/2010, 08:42 AM

I have a CPR hang on 'fuge that puts a lot of bubbles into the tank. It's causing problems with salt spray and the bubbles constantly getting into the u-tube of the overflow. I have a piece of foam around the outlet in the DT that helps, but that just makes the bubbles pop further out. I need a way to eliminate or at lease seriously minimize the bubbles. The fuge is set up with the outlet bulkhead 1.5" from the top of the box and is 1.5" in diameter. Because of the way it's set up, air is entering along with the water. Is there a way I can modify at the bulkhead to prevent the air entering?

I hope I've made sense!

No replies yet, but I've been thinking and would a downturned 90* elbow do the trick?

I have the same skimmer and the same problem. I added a 2" gray pvc cap, held in place with a stainless screw over the return. This is only tempory for me as it's going into a sump I plan on building next week. I had salt spray all over the place until I did this. I bought this skimmer on the advice of my LFS, what a mistake I would never recommend this to anyone.

I am having the same problem. I have the CPR HOB Skimmer and CPR HOB Fuge on my tank. For the skimmer, I bought the preskimmer/bubble trap adapter and it has worked wonders. I was considering a bubble trap adapter for the Fuge as well.

Are you talking about the small screen with the tie wrap that does fit?
