My Tank Thread
For the ESV 4 gallon concentrated bucket ... it's stated with some heat it'll slowly melt the harden calcium hydroxide on the bottom. My lazy method is to grab a clean (the bigger the better) PVC pipe and smash the crunchy calcium hydroxide in up and down movement until they're all dissolved. I've done this numerous times ... :D
Not sure exactly what you are doing, but there's no calcium hydroxide in it. :)
