With the recent Walmart rollback rollback of the $2.50 10% chlorine I decided to do some calculations using current prices. I have come to the conclusion that Leslie's Pool 12.5% is the best deal. I am in no way affiliated with Leslie's. I just want the best bang for my buck.
Here are my calculations...if my logic is flawed, i'd like the feedback.
8.25% $3.09 Walmart 121 fl oz
10.0% $3.43 HD/Lowe's 1 Gal
12.5% $4.50 Leslie's (sold in two pack) 1 Gal
To increase 15,000G pool 1 ppm according to Pool Pal
8.25% it takes 23 fl oz (5.26 ppm/bottle)
10.0% it takes 19 fl oz (6.74 ppm/bottle)
12.5% it takes 15 fl oz (8.53 ppm/bottle)
so if I had to raise my pool 1ppm per day i would go through
@ 8.25% 1.3 bottles per week roughly
@ 10.0% 1.0 bottles per week roughly
@ 12.5% .82 bottles per week roughly
Cost per month assuming 4 weeks in a month
$16.07 for 8.25%
$13.72 for 10.0%
$13.44 for 12.5% (WINNER)
So is this right? All bets are off if Walmart sells for $2.50 again.
