I have an Aquis 1000, and also a Sicce Shark internal filter.  Both intakes are a good 6 inches off the substrate, so it doesn't pick up a lot of the waste in the tank, but I try to give the substrate a clean once a week.  I'm happy to keep the vacuuming up once a week, rather than risk the filter picking up sand, or needing to be cleaned out too often. I just need a wavemaker or two to blow out the waste that is gathering amongst the rocks.

I might check out a few wave makers in the 1200 - 1500 lph range.

Cheers.

I really think I may have been over feeding them.  When it was time to feed, they seemed a bit sluggish and timid.  Now, when it's time to feed its a free for all, and they are queuing up.

I also bought an internal filter, I got the new Sicce Shark 800 from Vebas, nice unit.

Thanks for your help everyone,hopefully with careful testing of the water and regular water changes, I'm going to be on the right path.
