Trust me it works just follow instructions and u will be fine your skimmer will go nuts for about a week or so its normal just raise it up about 2 inches in the sump for a day and it goes back to normal
Did the treatment. 24 hrs later most cyano was gone. Did a 25% water change and changed carbon. 30 hours later I don't see cyano anywhere. Skimmer is freaking out as expected. I have collection cup draining back into sump for now. I will try propping it up to drop water level in the body. Corals look the same except for a pink milli which has 1/2 normal polyp extension.
I just dosed my 20 with cyano solution. I've been battling the red crap fir 2 months with just water changes and less feeding. It hasn't worked so I resorted to the chemicals
You will see it works your skimmer is gonna go nuts for about a week i raised mine up about 2" in the sump for 24 hours than put it back to normal and have been fine since
