Asthma-cant use chlorine. Need info on potassium shock

[PoolDoc]

It doesn't sound like you need any support from us:

1. You are already doing what Nature2 says to do.
2. It's failing to work (Surprise, surprise! . . . Not!)
3. You've demonstrated (again) that this process doesn't work.
4. Even so, you want us to help you make it work.

The only helpful suggestions we can make about "non-chlorine pool maintenance" is that they don't work, with one exception. You've simply given us more evidence for this conclusion.

Baquacil / Softswim / Revacil 'works'. It works fairly well the first year, and then deteriorates after.

It will *continue* to work, IF:
1. You replace your filter media (sand, cartridge) annually.
2. You replace (in one single event) 1/2 of your water annually.

PS. If it were *really* chlorine that is triggering your fiancee's asthma . . . he couldn't take a shower in most parts of the US, since THAT water is chlorinated, as well!
