Bubbles!!!!!!!

There is a big difference between water tight and air tight. The tape makes up the difference on the threads.

Well guys. Im useing a Proclear Wet/dry SL60. Here's the link. http://www.proclearaquatics.com/wetdry.html It's the first one on top. My pump sits inside the sump of it on the right side. I also have another pump next to it pumping water to my Fuge. I have a skimmer that sits inside the sump, but ive turn off my skimmer to see if it was the cause of it and they still kept coming out. I did change the hose from the pump to the tank and it's been 4 days and it hasnt cleared up. My return from my fuge is PVC that drains in my sump. Could that be the issue? I have the water level almost 2 inches high the the factory water line Proclear put on it. Someone please help these bubbles look very ugly and it bother the hell out of me, LOL

I have the same problem! I still haven't gotten ride of the darn bubbles. I have a panworld 100xx. I've tried putting filter around the return pipe, and putting live rock in the area. Nothing has worked. Somehow the pump seems to be creating the bubbles? I have an external pump with the pvc pipe running into the sump (over the edge). I think the air from inside the empty pipe never gets completly primed. If you find a solution let me know.

the panword pumps can pull air in around the pump casing. check the screws on the impellor housing. if not take the pump back to where u got it and exchange. thats the only flaw i've seen in these pumps.

I hadn't thought of that. Good catch Troy. It has an O-ring that seats on the outside of the pump impellor housing. If that O-ring is kinked or not seated correctly it could pull air.

You could also put the return line to pump to a higher point to increase backpressure and that will reduce the bubbles (but also flow will be reduced).

Ok that dont help me........

Try to eliminate sources of the problem one at a time.
1) Skimmer - you said you already turned it off and still had bubbles. Make sure it's off for at least 30 mins (60 is better) before you declare "I Still Have Bubbles :angry"
2) Turn off the pump to the fuge and see if they go away
3) Get a large (long) tub as a test sump. Put the drain from the tank at one end, the pump at the opposite, and some filter floss between the two. If bubbles are trapped in the water from your return, this should reduce them.

If none of these decrease bubbles, you either have air being sucked into a water line, or the pump's impeller is cavetating

Thank you. That helps me out alot. Your great.....

I have thread tape on all the threaded connections and and the rest are air tight from glueing, I have actually taken off the casing thinking that was the problem, looked at it and put it back on...tight! But I don't remember an o-ring?? I have also back flowed it by shutting off the pump and letting it ciphin back into the sump, to no relief. My water level is about 6-8 inches in the sump, so that couldn't be the problem. I'm at a loss!
