How about something like this? you will still need hose, ball valve to control flow and a pump. Size of the pump will depend on where you put it, HOB or in the cabinet. You don't need a lot of flow with these you just want the media to tumble a little. You can probable use a NewJet pump, maybe in the 1200LPH or less range. Not sure on that range, over here I''m talking about a Maxi-jet 1200 pump or less. Have fun!
