Awhile back my orange shoulder tang had two spots [ Ich ] to make a long story shot I used the above product. On the bottle one should use one teaspoon per ten gallons, at that point I was advised to cut that by a third, I did even better as this is new. I used two teaspoons for 120gal main tank, next morning got up to seven corals shriveled up. After two days [ 20% water change ] lost two and three hopefully will make it, one cap has turned chocolate brown..edges a lite color...Bottle reads as follows:
Safe for use in all kinds of aquariums, fresh or saltwater "including Reef and Live Rock " I don't find this to be true...Have added a bag of Chemi-Clean to sump
Yes all fish and critters are fine.
"NOT A HAPPY CAMPER !"
