1.Could you enlighten me on how i can setup the fx5 properly. I have 3 and 1 constantly has microbubbles, i have cleaned it and tried different media and it still gets the same result.
Probably a loose hose connected somewhere in the system, I had the same problem for a week then I realized where it bends that I didn't have the hose pushed far enough in the gromet rubber sleeve. Took it all apart soaked all the male and female ends under hot water then I connected them and it was much easier to get the fittings in all the way.

. Granted the FX5 isn't perfect but it's a good filter, I'd work to see if Hagen could not help me out....who knows could be a $15.00 gasket? I know this dosn't solve your problem with the Microbubbles but almost any problem has a solution. I've been wanting a 2080 or 2262 and have kept myself under control by saying to myself that I am lucky to have what I've got. Then again if the money is there?
