I am not in a desperate state yet. I keep cleaning to make sure it doesn't. I have patches on some rocks and the gravel. I have been removing it and blowing the rocks and sand. I have increased the flow and decreased feeding. I am now trying turning the lights off for 2 to 3 days. I have also purchased a more adequate clean up crew since I only have about 40 for 185 gal.
I know that the cleanup crew will not fix the problem but should help with more of the detritus. If this does not work I will consider your option.

Thanks again for the suggestion.
