ReefAddict1,
Might a peristaltic pump solve your problems. It does mean spending more but, this way, the effluent leaving you denitrator will be the exact same amount entering the unit. I believe it is like a dosing pump and it pulls water through at the rate you set it to, similar to a medical doser. This should take care f your air buildup and you should not require the power head that you are using to feed the unit any longer.
On a seperate note, I used the Korallin 1502 reactor. I got rid of it for the exact problem that your having- every few days or so. I would get an air buid up at the top of the reactor. What a pian in the A$$. However, to try and resolve the problem frst at minimal cost, I would throw the ball valves incuded with the denitrator in the garbage, which is where they belong and replace them with john guest valves, they are much more accurate and have less clogging issues. I believe that is what's causing your problem.
