Question about shock and chlorine

[Watermom]

I am asking Ben to see if I can find out amounts for you. I'll let you know when I hear back from him.

Actually, in the meantime, why don't you go ahead and start with the test with the bleach since that is the one amount we do know. I know it isn't the order he suggested above, but that's not going to matter.

Sounds good, Watermom. It'll be a few days before I'm ready to start testing; I'd like to let her heal up a little before trying anything else. She's much better today.

About the swimsuit: the outer shell is nylon, the inner shell is polyester, and there's a little spandex for stretchiness.

Spandex and syntehtics have been known to cause reactions.

Sounds like I should have her wear her swimsuit when I do the bathtub tests.

[Watermom]

When you are attempting to isolate a problem, you can have only one variable change at a time. So, she should NOT wear the suit as that is another variable in the mystery. You might do a test with just having her play in the bathtub with her swimsuit on without adding anything to the water. If that doesn't cause skin reactions, then you can rule out the swim suit as being the problem.

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!

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.
