As some of you may remember, I have been battling cyano for quite some time. I think i have it finally under control but i wanted to know the answer to the following question:

Is there any harm to the reef system in doing 10 gallon water changes in a 72 gallon tank for 5 days straight?

Last week i did that in addition to doing water changes about twice a week for the past month in order to clean out the cyano. I have had coralline bleach over the past few weeks. Corals are doing better and the few fish i have in there, seem to be a lot more healthy. I have tried to keep ph, alk, calc, and sg relatively balanced. However, can the amount of water changes affect the reef to produce coralline or produce any other negative effect?
