I had a rock-hard 1/2 full bucket of IO salt lying around that I was sick of chipping away at, but couldn't make myself throw away. So when I filled my ~80 gallon system I filled the bucket with RODI, and it made a nice ~1.09 concentrated salt solution that I poured off the top, and mixed with RODI water in the tank to make 1.025 water. I kept filling the bucket, and stirring for 10 minutes until all the salt was gone. Worked great. Just thought I'd share that stupid human trick, because I recall a few other folks were complaining about their solid IO bricks.
