As everyone has hit, HA is a sign that the water chemistry is off.
If it is true what you say and the HA is taking over corals and smothering.... I would suggest not adding anymore inverts and pick up a Sea Hare. This beast will clean up the HA in a day or two. However, that doesn't solve your water chemistry issue and you also have a sea hare that you have to keep fed.
