Sure you can add CYA to hot water to get it to dissolve. I tried drawing up the hottest I could get from the tap, and dumped the cya in. Stirred for maybe 1/2 hour, and guess what happened? Virtually NOTHING! Yup. Not really anthing worth mentioning. I was pretty amazed that it didnt' dissolve. I supposed I could have reached a saturated solution, but I don't think I did. You're still going to have to wait a week for it to properly show up. Personally, I don't mind the wait because I know how hard it is to remove if I overshoot. Just stock up on some POP.
