First of all, here are my tank parameters:
55 gallon FOWLR 60 lbs live rock with 5" DSB
Nitrate 10 ppm
Temperature 80 degrees (I keep it at a steady 80 degrees with good air conditioning during the day and heating at night).
lighting-2 65 watt PC 50/50's
Skimmer-red sea prism
Aquastep UV sterilizer
I have 3 fish in the tank-Bicolor foxface, three stripe damsel, and a cleaner goby.
The foxface seems to be the only fish that gets infected and it happens every night. In the morning, when the lights come on the poor guy's fins are covered with white spots. The cleaner goes to work and usually has him cleaned up by mid afternoon. But, this happens every night.
I am trying to avoid using any sort of medication in this tank if at all possible. Has anyone had results with lowering their salinity to eliminate the parasites? If so, how long does it take and does it destroy all the eggs that are germinating as well?
Also, does anyone else have any idea what could be causing this poor fish to be the only one that is getting the characteristic white spots? It seems odd to me that the other 2 fish are fine.
Thanks everyone. I'm scratching my head on this one.
