my tank is having an issue with crud building up all over the place. mostly on my frogbit side. i dont have a filter on that side because im using hob and those seem to kill my forgbit. so do you think a power head would help kick up some of the crud and push it to my filters on the other side? when i do my weekly water change i try to pick up as much as i can but i cant do a gravel vacing because of the plant's roots.

any ideas what i can do to kick up some of this stuff and keep my frogbit alive? a canister filter will be in my future but the funds are low for fish now-a-days.
