I have been doing some reading.Scarey I know.I was wondering if anyone has tried this.It is called suspension growing.Mainly for sps corals.It says tha they will grow better and faster due to the coral being suspended and getting good water flow on all sides of the coral.This is directed to propagation more than personal tank use.It also says to use a bright sand bed to reflect light to the bottom side of the coral.I plan to try this in our propagation tub and see what happens.Has anyone ever tried this?
