how often do u clean your filter out

Roughly twice a year. And by clean out, I assume you mean dismantle it and scrub it down. If by clean you mean change filter pads, etc... then I do this roughly monthly. Any more often than this you run a risk of losing a good amount of beneficial bacteria that actually keeps your water clean and clear.

Doesnt hurt to regularly clean the impeller if you rfilter has one that is accessible
