Im setting up a FX5 for my 150 gal. And i was thinking of plumbing it to a undergraval filter and filling the FX5 with bio. So my ? is it worth it and will it damage the filter??*SUPERSMIL
Were it me,(and it ain't) I would use a couple powerheads in reverse flow, and the FX5 to clean the water being pushed under the plate and back up through the substrate by the powerheads.
