In my tank i used circulation power head to blow waste into filter intake (you can hide power head behind your decor, I also position my filter output to blow along side the back tank wall, you will need to trials and errors to get it right with the flow rate. I never have to vacuum or clean my sand substrate ever, it's always clean and water always sparkle clear minus feeding time LOL cause pellets giving out fine dust on water surface and my fish pooping same time too but my water back to sparkle clear less than 1 hour.
