I removed my bioballs about a month ago and filled the empty chamber with a sponge as the water from chamber 1 of my biocube was making too much noise falling into the now empty chamber 2. my nitrate levels have since dropped from about 10 to 7.5 ppm.
did you have mechanical filtration before the bioballs
