Ruby ReefKick-ICH PRO 2.5 Gallon Cube

I've had ich in my system for a while and as long as the UV sterilizer was on, I never saw more than a few spots and didn't lose a single fish to it. I decided to try this treatment and see if I could eliminate ich. The instructions say to turn off skimmer and UV during treatment. I did that. I used it conjunction with Rally like the instructions say too. It says to use for a period after the last spots are visible. The only way tI would have ended up with no spots on fish would have been if I let every single fish in my tank die and had no fish at all.Using this product and following the instructions was the worst decision I have ever made in over 8 years of having multiple large reef tanks. Every fish that got spots had them increase throughout the entire 13 day treatment. Not s single one showed signs of improvement during the entire treatment. Almost every fish died until I turned back on my UV sterilizer after the 14th day. Then within a couple of days the last few remaining fish got better. As fish were dying and some were hidden under rocks, my skimmer wasn't online to help with any nutrient export. The water quality declined steadily throughout the treatment. I ended up with just a few fish left, a huge problem with hair algae and some dead corals.
