Thanks Chem Geek! That "1% other" in their formula was really my only concern. ....just look at what "1% other" did to Superman in the 3rd movie!!! haha.. you never know! So just wanted to make sure it is safe to use this specific brand. Thanks to all!

I actually stopped at Ace on Friday to get Boric Acid and some other cleaning items. When I asked them to show me their muriatic acid, it is in a bottle that is labelled muriatic acid and is sold as such. Then, when I asked them for Boric Acid, they sell it as: Harris Boric Acid Roach Powder which is 99% Boric Acid. The attached MSDS states it is 99.0% pharmaceutical grade A Boric Acid. (the MSDS states remaining 1% of components are non-toxic / non-hazardous) Before I pour 2 bottles of roach killer into my freshly cleaned hot tub... can somebody confirm that this Harris Boric Acid Roach Powder is an acceptable source for the boric acid that is discussed in the forums. Thanks!! http://pfharris.com/msds/Harris%20Boric%20Acid%20Roach%20Powder%20with%20Lure.pdf ps: THANKS to those on this forum that are very knowledgable about chemicals / chemistry and help the rest of us that have basic questions. On other forums for other parts of my life, I am more of an "answer-er" than a "question-er". So I greatly understand how much work it is. THANKS!
