Spring TX: $25.46 for 14 gal 11% at Napco chemicals - That is $0.129 per oz Cl, or $1 for every 7.7oz Cl.
Most of the TFPers here avoid using too much in the way of powders as they add unwanted ingredients to our pools such as CYA or Calcium. When used exclusively the CYA or calcium gets too high and causes problems and the only way to resolve high levels is to drain and replace water. That's not always possible in areas where water is heavily restricted.
It rains here all the time and that pretty much fixes it for me. Just drain a little and let the rain fill it up.
Just got back from our local (Houston / Heights area) Wal Mart and saw they have their 1 gallon jugs of 10% chlorinating liquid on 'Roll Back' to $2.50...with quite a bit in stock.
Quick question about Bleach and entering it into the PoolMath calculator. This Clorox bleach at Walmart contains ACTIVE INGREDIENT: Sodium Hypochlorite: 8.25%, OTHER INGREDIENTS: 91.75%, TOTAL: 100.00%. (Yields 7.85% available chlorine). Contains no phosphorus. http://www.walmart.com/ip/Clorox-Concentrated-Regular-Bleach-121-fl-oz/21618295 I should enter it on the FC line as 8.25 and not 7.85 correct? Is this the right type of Bleach to be buying for the pool? Thanks for the help!

Last year I could get 4 bottles of 128oz 10% at Atwoods in Oklahoma for $7.99. That's $2 a gallon of 10%. Today the price was $10 for 4 gallons, which is still good compared to walmart, but I hope they lower the price back to $8 once the season starts.
