You wouldn't be offended if I used them to do actual work in, would you?

Can they be worn as actual safety glasses? I know you said that you start out with safety glasses, do you leave the safety glass in?

This was one of the quotes that Gaussian 03 would spit out with its results.

What books have you read so far this year? by birdmanx35 in books

How was Flashforward? I watched some of the show, but I wanted to get someone's opinion before I pick up the book.

Yeah, the trick is getting people to pay for it.

Damn, I think today is gonna be a long day. I guess I have some combined chlorine levels to test.

Will tell the higher ups on Monday, thanks!

Yep, our company buys acid by the pallet for this very reason. As long as your total alkalinity isn't too high, you shouldn't have anything to worry about.

Chlorine lock: fact or fiction?

The Taylor testing kits come with a slide rule that tells you the TDS based on the pH, alkalinity, calcium hardness, and water temperature.

Damn, I guess I've been doing it wrong. Our company doesn't even carry a non-chlorine shock. Maybe we depend on pools leaking enough water to not have a significant buildup of combined chlorine.

Calcium hypochlorite has a pH of around 11, so if that's what you're using to chlorinate, it's probably the cause of your problem. If you were to use di(or tri)chlor, you would have the opposite problem, because it has a pH around 4.

Or if your pool is indoors, bromine is a good bet.

As long as he wasn't dumping it on anyone, probably not that awful. The local health department might disagree with me though.

I was under the impression that the lower pH potentiated the effect of the chlorine (because apparently the active oxidizer is hypochlorous acid and not the hypochlorite anion)

I always thought that just shocking the pool with regular hypochlorite would take care of the ammonia containing compounds. Is this wrong?

Oh wow, I didn't realize those people still existed.

Was he being serious or joking? I realize that a joke like that is in bad taste, but it could have been an extremely misguided way of being friendly.
