Background. 3-4 weeks ago, I had an outbreak of crypto in the reef. I observed it for about 7-8 days, then caught sick Helman and white-breasted surgeonfish and treated them in a quarantine tank. The fish did not survive. The "sick" aquarium was treated with UV for almost the entire time. However, since the fish remained in the reef, the crypto cysts did not go away; only the freeloaders died. Now the story. On March 18, I bought several fish from a store. They were in quarantine for 3 days, and no external signs of disease appeared, so they were released into the reef. On the second day after the transfer, the zebra and Helman started showing signs of crypto. It was decided not to delay treatment and to conduct it directly in the reef. The medication used was Seachem ParaGuard. Dosage: Day 1: 1/4 of the recommended dose Day 2: 1/3 of the recommended dose Day 3: 1/2 of the recommended dose The medication was added in the evening after the aquarium lights were turned off, and the UV was turned off for the night. On the third day of the outbreak, there were no signs on the fish's bodies, only residual spots on the body and 1-2 dots on the fins and tails. On the fourth day, the fish were completely clean. Now about the corals. All corals react to the addition of the medication almost instantly: LPS retract fully, and SPS become "bare." This reaction lasts about an hour, then within 1-2 hours, the corals return to their original state as if nothing had happened. Shrimp, trochus snails, hermit crabs, strombus snails, and other crawling creatures do not react at all. That's the experience. Maybe it will be useful to someone.
