Awaiting delivery on a new tub and I am looking to add borates to my water after balancing. I prefer to use boric acid rather that the borax/MA method. Where have you folks had luck finding the stuff?
I see the local big box stores carry roach killing powder which according to the MSDS is 99% orthoboric acid. Would this suffice?
