Flow Help!!!

[huskerreefer]

My OEM pump in the biocube is crap and keeps losing flow. I added a Korilina nano powerhead but it seems to be not as strong as when it went in. What can I do to a) either fix the current equipment to get better output or b) what is the best/cheapest replacement for OEM pump?
Thanks!

Clean the korilina good, there is probally crap around the shaft, and for replacement pump look into rio pumps.

For the Korilina, other than taking of the front cover and getting at it with a brush, is there any other method to clean it? I had tried that last night when I did a water change and it didn't seem to make it perform any better. What size rio is good for a 14Gal BioCube?
Thanks!

I just cleaned my koralia 3, took off all the algea that was on the top, and it is pushing at least twice as much water as before! If you have already done that and it didnt take care of the problem, then its probably a problem with the powerhead itself.
