I had the same type of problem in my reef tank. I had a hob filter a uv and a skimmer. I had fish always dying of ich. I switched from a hob filter to a sump, lowered my salt lever to 1.025 from 1.026 and bumped the temp up to 81 from 78 slowly of course. It seemed to help a lot. I did sell the tank a few months after so I have no long term feedback but I did not lose anymore fish in the 3/4 months that I did have the tank. Higher temp and lower salinity is good for fending off diease.
