Anyone know the percentage of Road Runner Ice Melt? Also, anyone heard of any negatives of using this? As it's not 100% Calcium Chloride - I want to be careful of what else in the bag I'm adding.
Please try not to hijack others thread. I answered this same question you posted in your other thread - http://www.poolforum.com/pf2/showthr...lcium-Chloride

If you start cross posting the same questions in multiple threads, it's only going to lead to confusion. Ben Powell and the Mods are no longer actively managing this site (they are occasionally posting but not doing much admin activity). Therefore there is no one around to clean up and combine duplicate threads. The Pool Forum will start getting very messy if folks don't take a lot of care with posting questions.

Thanks

PS - My answer to your post is this - be careful with standard road surface deicing products as they can contain trace levels of metal impurities. That's not at all something you want in your pool.
