Been doing it for several years now. Just a maxijet 400 and a old salt bucket. 4 tblsp kalk and 4 gal water , refill every 3 days. I don't worry about sucking up the stuff off the bottom. I currently run mine off of my controller at a rate of 5 seconds on once every half hour during the lights off period. I usually wind up having to replace the MJ impeller about once a year.
