if u turn yer sump into a refuge u will want to turn the GPH down
yer prolly better off havin a seperate fuge so u can keep yer gph up high threw the sump for over all water flow and have a fuge on the side with a less amount of water flow
unless i modify yer sump to have a low flow area which im quite sure u can do with strategic placement of glass baffles
most fuges ive seen have a clean up crew wth snails crabs etc if u have a deep sand bed in there u dont want anything thats gonna burrow deep |
