Anyone ever hear of this?
There is a radio show in my area on Sat, called:
the backyard bay...http://backyardbay.com/
I started listening to it a while back and it was informative.
They constantly plug how this should be the only salt you consider for your salt water pool...
Anyone know if this is legit, or is it just part of a big AM radio infomercial these guys are putting on?
