Question about shock and chlorine

[BigDave]

Water bear asked:

...Is the rash on areas that were covered by her bathing suit or on areas that were not?...

So, if the rash is on skin touched by the suit, the suit may be causing or contributing to the rash.

Like Watermom said - change only one variable at a time to avoid confounding your results.

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.
