Did you ever get that refractometer? I think salinity is my problem. I use a hydrometer and keep my salinity at 1.025. I put one of those floating temp/hydrometers in my tank to check the temp against my stick on thermometer and the temp was 80 but the salinity was only 1.021. WOW! I'm lucky my other corals are doing so well. I will be raising my salinity with top of water until I get it where it should be. No wonder my tangs never got ick! I think I will be buying a refractometer pronto.
