After doing about 20 gallons worth of water changes, my KH is still sitting in the 12-13 range. When I mix up a fresh batch of saltwater, it tests in between 8-9. I am using the API KH test, and I know they aren't exactly renowned for their accuracy. I guess I will just continue the regular water changes and hope for the best. The only thing that is showing signs of stress is a blasto, however, it is a relatively new coral. It is possible the issue with the blasto isn't related to the KH.
