My aquarium will have to go sumpless for a while and water changes will have to be conducted in the meantime, the SPS colonies are in the upper part of the tank (naturally for 150W lighting) and on changing the water will be exposed to air for a short period. In the wild i am aware that reef building corals are exposed to air in intertidal areas, im just wondering what people's views are on exposing SPS colonies to air for 10 mins or less in a captive system while water is changed every 3-4 weeks or so. Im not so sure its a great idea given that their environment will change rapidly with the local addition of new water and given SPS sensitivity to instability and rapid shifts in water dynamics, but id like to hear everyone else's views. Specimins in question are some Acropora Sp., Seriatora Hystrix and Montipora Sp.
