A few querstions on Muriatic Acid and Dry Acid
1) Is it me or does anyone else in the Northeast - specifically NJ - have a problem finding Muriatic Acid in stores? I looked in a few Home Depots and they said they no longer carried it. Any suggestions where to look?

2) It seems most people pour it in their pool rather than the skimmer. What is the benefit, and is it dangerous to pour it in the skimmer?

I've been using dry acid for Pools (bought at HD). I usually fill a container with pool water, mix in the dry acid and pour in the skimmer.

thanks
