I am in the process of adding Sodium Borate to my pool water and needed a lot of pool Acid. I got some at Home Depot and more at Do-It Center. While in the process of applying, I noticed an astounding difference between acid from Home Depot and Do-It Center. Upon closer examination of the bottles it turns out that Home Depot's acid is 14% strength and Do-It Center is 29% strength. Moreover, Home Depot is $1.50 more expensive! So I was getting halve the volume at a higher price! Just thought you might want to know.
One more tip. In my search for Borax I found two boxes at one Walmart and two boxes at another Walmart. I did not find it anywhere else. So I ordered bulk online from SoapGoods. With the cost of shipping, the price is about even but you don't have to run around.
