Marc - The only recent changes/stressors were that I began using ZEOvit additives, and I did a water change on Saturday. However, according to the article you linked ...
"Does stress cause "Ich"?
Stress and poor water conditions do not cause marine "Ich", although they will lower a fish's resistance to infection and impair their immune system. If C. irritans is not present in a tank, it doesn't matter what how stressed a fish may be, it cannot get infected. In a tank where parasites are present, stressed fish are more likely to show signs of "Ich" before more healthy fish, but the healthy fish are just as likely to become infected as the numbers of parasites increase. Those fish species that are less susceptible to "Ich" or those individuals that have an acquired immunity, may show no signs and may not get infected."
Also, according to that article, it's not unusual for the fish to clear the visible infection, but as the spores release new parasites, the fish can be re-infected. I plan on soaking the food in garlic and adding more nori to their diet. I'd like to avoid a hyposalinity treatment if at all possible.
jnarowe - Yes, I'll try to feed more often as well, although this will require the help of my wife. Thanks honey (my wife, not you Jonathan

bleedingthought - The 4-way is rocking along. I had to remove the drum and clean it off once more due to the waterhammer, but this corrected the problem immediately.
