You guys have been an unbelievable help in helping me break away from my pool guy saving money as well as being proud in how well the pool is looking. I have a 34,000 gallon plaster pool with great numbers with the exception of CH.
According to poolmath, I need to add 554 ounces (or about 34 pounds) of calcium chloride. is there any real difference in the quality of calcium chloride to account for significant price differences between products? I know de-icer is much cheaper but I cannot locate any now during the summer (plan to stock up this winter for next season). I was looking at these two products at walmart:
http://www.walmart.com/ip/Pool-Mate-...easer/36939139 costs $25 for a 25lb pail
http://www.walmart.com/ip/In-The-Swi...-Pail/44441492 costs 40 for a 25lb pail
Lastly, any suggestions or advice for how to add this much product? I have heard conflicting recommendations to pre-mix in a bucket as well as some comments about the product not completely dissolving and hardening on the bottom of the pool. Are there any restrictions on how soon someone can go swimming if I add it all at once or over the course of a day?
Thanks again for all the help so far. I have already recommended the site to a couple of friends and neighbors who are having issues.
