Another project on my tank was to get the brightwell bio brick running a certain way recently I was informed the correct way of running this brick to encourage anaerobic bacteria was to run water thru the block something like the pic below.

So off to work i went I started with building these 2 supports.

Then glued them to sump

Next I cut a tee in off my return pump line with a valve to control flow.



And finally it running, so enough water should go thru that water runs off each nipples.
