Question about shock and chlorine

[donovan.lambright]

Got it. I misread Waterbear's post as implying that those materials can react to pool chemicals, not that they could cause a reaction themselves. Thanks for the clarification!

My Taylor K-2006A kit just arrived!

You sound like a kid at Christmas!

In order for me to figure reasonable dose, I'll need to get some kind of estimate of the gallons your tub holds. You can determine that by:

1. Adjusting the flow to a reasonable level, with the drain open.
2. Filling an empty milk jug and timing how long it takes to fill.
3. Closing the drain and then filling the tub, and timing that interval.
4. Then, dividing the tub interval by the jug interval to give approximate gallons.

Be sure to have her get in, and make sure you haven't selected an overfilled level.

With many tub surfaces, you can mark the line with a magic marker, and then remove the mark with rubbing alcohol. But, some surfaces are porous, so test this with a small inconspicuous mark, before you do anything more visible.

Instead of a magic marker, could a piece of some sort of tape work?

[PoolDoc]

Waterproof tape, like Gorilla duct tape or Scotch 33+ electrical tape -- Yes.

Yeah, I'm pretty excited to have the kit. LOL

I have a bit of a domestic problem and need your opinions. My wife is very uncomfortable with the idea of doing the tub tests. I've talked to her about our conversation and the BBB method you have developed. She is pushing pretty hard for me to simply drain the pool and start over again using the BBB and Intex Recipe that Ben posted. I've explained that, without testing, I can't guarantee we won't have similar problems after we start over. She says she's willing to take that chance. I told her that we would be done with the pool if that happens because I'd have no way of tracking it down.

I know you can't tell me what to do in such a thorny spot. I'm just looking for opinions.
