Microbubbles

  • We are currently upgrading MFK. thanks! -neo
Alright. Thank you for everyone that has given me options to try out. The answer to the problem was the water level in the sump. I guess my pump was sucking a lot of air because the water level was too low. Now I feel like an idiot.

No problems Bro...we all been there, and done that...glad it was a simple fixation;)
 
Sorry to bump this old thread, but I'm having this issue as well. I've probably had it setting up my 450, but now that I actually have decent lights I can see them.

I have my uv in my sump, which had a hose that wasn't on tight and making bubbles...I thought it might be this, as some bubbles might be getting sucked into the pump. I've since solved this issue, but the bubbles are still there.

It is an external pump, and I'm using hose. I've tightened down all the hoses with metal clamps around the barbs. There's about a 12" distance from the tank to the pump, with a ball valve in the middle. If I turn that ball valve, the bubbles seem to stop, but it could just be the flow slowing down so I don't notice them.

I've tightened every thread as much as I can. There is about an inch difference between the hole in the tank and the intake on the pump...the tank being an inch lower. The water level is about 10" above the hole. Could this 1" climb be causing an issue? Could the problem be inside of the pump itself?

yes check out your propeller inside. if it looks normal then check everything else
 
I moved the pump down so its no longer above the tank hole, but below it. I also took apart the bulkhead on the sump and put it back together. Took apart all the plumbing and put it back together. The only thing I haven't done is taken apart the pump. So I guess its only logical that its in there.
 
I had the same symptom , it turned out to be on the suction side of the pump inlet hose barb fitting. No amount of tightening the clamp would solve it. I removed the hose, wrapped the hose barb with a coule of wraps of teflon tape and reinstalled the hose. No more micro bubbles

Excellent, I will try this. Haven't had a chance to mess with things again yet. Probably will mess with stuff on Tuesday.
