I would chalk it up to "one of those things" and go back to 40ppm. I'll bet you stay there all Summer.

Say, were you chit-chatting on that new, waterproof phone and having an adult beverage when you did that 25ppm test? Yep....that explains it!
LOL..well, now that you mention it, I did see 3 tubes.

BTW, I highly recommend that Uniden phone from the "L" store. It is awesome! It is totally waterproof, and we made sure of it. My 2 year old dropped it in the pool. It floats to the surface, and works like a charm. Well worth $60 IMO. That's 2 jugs of Baquacil for me Of course, I am on the BBB plan now, so I can buy new toys for the pool, and still save $$$.
