Last time I cleaned my AC50, I just took the sponges out and the bio-media out, rinsed them in tank water, and stuck them back in; didn't bother pulling the filter basket out. I haven't checked on the impeller in a while, so I decided today to tear the whole thing a part- checked/cleaned the impeller and then pulled out the entire filter basket instead of just pulling the media out. Under the filter basket there where AT LEAST 8-10 RCS of various sizes swimming around. Talk about a suprise! Maybe I should check down there a little more often!
