I was in and out of town a few times, so I put off the QT process. The Gramma scratched occasionally, but other wise seemed fine. Came home to find the hermits and cleaner shrimp having a Gramma feast. The rest of the tank inhabitants are fine. It had obviously been dead for awhile and picked at so I could not identify any spots or injury that may have caused its death.
I checked all the parameters, the only reading out of the norm was the PH. It normally runs 7.8-7.9 depending on when I check it, but it is 8.2 today. I was suspecting the tank has Ich because I never saw flukes in FW dips. The only other difference in the tank has been a dusting of brownish algae on the glass, sand, ricks, etc the past week or so. It does not disappear when the lights are off, and blows off the rocks and sand easy enough with a turkey baster, but there are white filmy that blow off the rock too.
My thoughts are feeding changes, due to the automatic feeder, and Ph changes stressed it out and it succumbed to Ich.
My plan is to move the two clown fish to the QT and start ramping up Copper Power to 2.0 for 14 days, then switch to a clean QT and observe, but I never seen spots on them and have rarely seen scratching from them. What level should I start the Copper Power at? Any suggestions for additional baths as part of the treatment/QT process?
