Thadius - can you give us a little more background on your tank? Was it just recently set up? How long ago? Do you have
live rock/live sand? What are you testing for and what are the numbers?
Fish are very sensitive to high
ammonia levels, so if your levels are too high, he could very well be suffering as a result of this. By the way, many people have mentioned that the Hagen kits aren't so reliable. You might want to invest again in some good Salifert test kits.
Have you tested the sea water that you're collecting? You never know...you could be introducing parasites into your system. Check the
nitrate/phosphate levels as well in the water that you're using for your water changes.
Are you using
RO/DI water for your top-off?
If the water that you're collecting is at all contaminated, then I would suggest switching to a salt mix.
Let us know how you're doing....
