Acclimation Tip: in summary of this section on acclimating coral, it is my recommendation that all newly imported coral, and coral from previously unknown levels of light, be placed in systems at a depth no less than 20" under higher output fluorescents and metal halide lamps (assuming the intensity of such light is appropriate after the animal overcomes stresses). Acclimation to the final level of display can be approached gradually in increments of 4-6" weekly or less often depending on coral behavior. Dedicated aquarists may wish to build or buy simple, weighted building blocks (like cubes made of acrylic) that can be used temporarily in an open space of the aquarium. Small blocks or shelves will help to acclimate a coral without concern in a well-stocked display for finding space along the rockscape incrementally in a path to the final position. Another interesting technique is to place a stack of coarse plastic window screen pieces above the new coral to filter light (perhaps on the aquarium cover) if a coral is to be placed immediately in its final position. Enough sheets for each day of the two to three week acclimation period will sit above the new animal. One sheet of screen is removed each day until all are gone, providing a gradual and filtered period of adjustment for the new coral. One can imagine many other ingenious ways of attenuating light during the critical acclimation period of a new reef invertebrate. Raising the light canopy for a new coral is not recommended with other established coral in residence. Indeed, after an extraordinary trip from a coral farm or wild reef to take up residence in a beautiful display, light shock should not be an issue to the empathetic and well-informed reef aquarist.
and like prideprops say give u zoos a dip they are prone to fungus and Zoa eating nudies u don`t want that ......
