Hey Matt, I in no way want to knock your treatment of hypo and maybe I am misunderstanding your post, but... I think you may be playing roulette with the new fishies. I tried to shave some time off going fallow back in month 1 of my set up and had a tank full of fish with no signs of crypto, so i decided to spoil myself and picked up a purple tang from Reefwise. I QT'd the tang and an anthias trio for 4 weeks and then placed them in my main tank. Two days goes by and everyone seemed fine, I feed one morning, head out the door, only to return 6 hours later and my tang laying on his side absolutely covered in crypto. Absolutely the worst case of marine ich I have ever seen in person... Made me sick to my stomach. The anthias were also covered, just not as bad.
The crypto had to have been in my system, because I treated cupramine and prazi pro combined for 4 weeks and these fish were all eating and healthy. I had to tear my rocks out and catch roughly 12 fish, dip and re-QT them. I saved my tang, but my anthias trio perished. I have now been fallow AGAIN!!!!!! for 4 weeks, with my fish in a 75g QT, all doing fine. I am remaining fallow for 4 more weeks to be on the safe side and will NEVER add a fish, rock, snail or coral to my tank that has not been QT'd for 30 days. I refuse to deal with this S%*T again.... I originally tried hypo and it needs to be much lower than you stated yours was, in order to be effective, otherwise you are stressing your fish and corals for nothing! Corals and rock wont survive true hypo treatment.
Again, I may have misread things, because I know you are a methodical reefer, but I thought I might share that with you! I love your tank btw.
