Waste is just food for other organisms. At the bottom of the chain is bacteria is it not? This bacteria is either living from what the bacteria is producing or what is attracted to it surely. Other than the possibility of hydrogen sulfide being released from disturbing a thick bed of detritus what else is there to worry about? Having said that why disturb it anyway. I may be barking up the wrong tree here but that's the way I understand it.we cannot agree its intert mineralized waste, since its killing tanks that do home moves without following surgical order of ops. There is marked consequence in viewing detritus as neutral, in all cases. somewhere that loop you describe Lasse gets interrupted, and bad things happen, for many tanks that compact in waste.
