High temp speeds up life cycle, which will worsen infections, unless you have removed everything from the tank, hyposalinity prevents adults from being able to mate therefor no new babies. therefor cycle ends. That said, 12-16ppt is the recomended low for this treatment... which dont know about you... but would be hard on the corals... the "Safest" way is to remove fish to a QT tank hypo them for a week then leave them in QT for 6 weeks wile the ich in the MT goes through its life cycles without hosts and therefore dies. That said higher temps could shorten this process in the MT to less then 6 weeks... but I havent read anyting about it, therefore would have to test it myself... which I dont have the equiptment to do right now.
Though I also swear by cleaners as a preventative, in my monster setup I plan to have around 10 of them. I don't know how UV is natural... but thats just me lol (in nature UV light isnt strong enough to kill ich otherwise it wouldn't exist), but I would never use UV either way as it kills off my phytoplancton and zooplancton that feed my corals/clean my water.
