just a couple ideas........ try feeding the turds in a different container. Some will, some won't...kinda depends on your patience level. I clean my tank THOUROUGHLY about every 3 weeks. I empty all water, rinse all rocks and other tank items under HOT water, and clean the inside and outside glass with reptile safe glass cleaner. In between, I clean the tank PARTIALLY about every other day, but I'm not too anal about it (sometimes it will go a week). By partial cleaning I mean just emptying half to most of the water and refreshing it with new. Just remember that even if your tank looks clean there is a lot of bacteria that is invisible to your eyes. Try your best, but RES are extemely hardy... so don't worry too much.
