spin down filters?

  • We are currently upgrading MFK. thanks! -neo
i called rusco "spin down filters" they said if i have a pump that does over 1gpM then it will work fine and will even back flush the filter during water changes so ill never need to wash filter socks or other mechanical sponges.. im thinking about making the bio tower out of 4 inch pvc pipe and filling it with lava rock or ceramic rings? just not sure how well the water will flow threw it or how big of a pump ill need
 
Split the FBF onto a separate line with a valve of sorts and then you can run the SDF with whatever flow that you want to and dial the FBF down.
