Hi TFPers! Happy 4th weekend.
I usually purchase 12.5% from my local mom/pop pool store. Price is fair. I use the calculation to figure out the price per oz. of NaClO. I calculate it by hand and it is quick, but recently stumbled upon this website from someone's TFP thread if anyone cares to bookmark it: Chlorine Price Per Ounce Calculator
With a sale on 10% chlorine (Kem Tek) for $4.99 for 2 gals. at my local OSH, and even when not on sale, the 10% is cheaper per oz. of NaClO vs. the 12.5% pool store stuff. The sale at OSH makes the Kem Tek stuff $0.20/oz of NaClO. Normally at Lowes I can get it for $5.86/2 gal. of the 10% Kem Tek which is $0.23/oz of NaClO. The reg. price at my local pool store for the 12.5% is $17.98/4 gal. which is $0.28/oz NaClO. What I am getting at the pool store is HASA.
The problem I am having is that even though the Kem Tek is a great deal right now on sale, I will have to still buy more of it to produce the same desired effects. Thus, I will be buying it more, which means more trips, more gas, and more waste/recycling on the environment vs. the pool store stuff which is a closer drive for me, and the bottles are re-used vs. having to be recycled. Therefore, wouldn't the 12.5% be a better deal? Even if just looking specifically at the volume I will need to equal the 12.5% over just one summer period, wouldn't the 12.5% be the best choice?
