What is the best way to get the solid waste material up off the bottom of a tank?

I am having issues keeping it lifted and pumped up. I think I need two kinds of filtration, or a larger biofilter?

I just cleaned my tank out about a week ago and it was dirty after 2 days, alothough it does appear to be a little more clear now.
