We have to report that our Royal Gramma did not survive the hospital tank hyposalinity treatment. He was the most affected by the ich. Everything was going well. All the ich spots were gone within a few days. He was very active and feeding. Then all of a sudden he just died. The mandarin and the purple firefish show no ill effects.
We are one week away from starting to increase the salinity slowly. My wife read Albert Thiel's posts and felt we needed to give then some additional time.
Sorry to read about the Royal Gramma and thanks for the clarification on what you are doing ... I appreciate it.
