This is a good question. Although you have a diffrent situation then most due to the feeding regiment allot of your corals need. Personally I am going to go on the limb and say removing it once it accumulates as you are is probably jump starting your bacterial activity. Yes I think it could be removing some issues but eventually the hazards would out weigh the benefits in a very deprivental way. Of course this s just me jumping in and and truth be told if I was contemplating this with my system I would do a study of both situations to derive my conclusions.
