Hi ,
Today I started my quest to get my borates up to 50 ppm. I went to home depot to get some muriatic acid. The first thing I noticed is that it looks like water. I haven't purchased acid since last season. The acid I had from before was yellow in color. I looked at the ingredients and it has 14.5% acid. 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
