Or would they be too strong? If o.k., what's the smallest particle size sand substrate recommended w/out it blowing all over (e.g. could "Southdown" size be used)? Thanks.
I would prefer aragonite reef sand, the coarser 2-3mm sand. This is a good plan for tangs and butterflies fish prone to ich that love high flow. Otherwise you could just use a couple 6060's on timers or a couple 7400/2 pumps.
