I have an emp 400, I have a layer of cut to fit bonded filter pad inside the reusable cartrege and another layer of BFP in front of that. It dose a good job at cleaning the water, however no matter what media I put in the silly thing it spits out bubbles (macro and micro). It has even made what looks like betta bubble nest right infront of the filters spillway. I cleen my tank diligantly and do large WC's every 3 days, and I have made sure the intake is seated properly and I cleaned the filter inside and out to no avail. Any ideas on what could be causeing this or how to fix it?
MAN that thing moves some water, so as soon as its all seeded up with BB (im guessing 4 weeks?) Im gonna ditch the 400. Thanks for the advice tho guys.
