Unfortunatly I didn't have any left over acid jugs from last season to see if they lowered the percentage of acid. I know the acid I had before would almost knock you out if you caught a smell of it. This stuff doesn't do a thing. Has anyone else noticed any difference? I am in California Modesto area.
Chem Geek when you calcualted the amount of acid per box of borax what percentage was it for? Maybe this is the reason why I am having to add so much acid to my pool to get a change. If in fact the percentage has changed. Well off to add some borax and acid to the pool. cya

I had the same problem. Lowe's still has the strong stuff but who knows for how long. The thing that burned me about HD was the price was the same as before but half the strength. Lowe's has the same price but 29%.
