I started my fallow period a couple of days ago and realized that a very integral part of my algae control is now in a QT/Hospital tank. 90 gallon tank is moderately stocked with mostly LPS coral, 3 Skunk Cleaner shrimp and a couple dozen assorted snails and hermit crabs. Is there anything that's reef safe that I can add either proactively, or later on should the need arise?
UV? Crabs? Urchin? All of the above?
