I agree, it just may do that, but that brings up a thought I had last year, and still do... Why doesn't the added earth scent, woodland scent, etc. get neutralized in the commercial brands as well? I'm sure it has to do with chemical reactions somehow, but it's just a thought.

By the way, I went to buy some of that commercial pool peroxide and decided not to in the end. I have a three year old and I just don't need another chemical that I have to try to keep away from him. They have the gallon jug in a thick plastic bag with warnings all over it about avoiding skin contact and about it being harmful or fatal if swallowed. I'll just stick with the store bought brown bottle stuff as well. Safer that way and it has already proven itself twice for me so far.
