First Post - ZERO Chlorine

[donnah1301]

Thanks so much for the help. I did get a decent test kit and am good to go. Thanks again!

Just so you know: there is just one "decent test kit" that's widely available locally: the HTH 6-way kit, made by Taylor and sold by some Walmarts. It is fully compatible with the K-2006, and since the chlorine test is OTO, it continues to work when chlorine levels are above 5 ppm.

The Taylor K2005 is sometimes available locally, and is a good kit for everything EXCEPT testing chlorine. But, since it uses the DPD color match test, a zero chlorine reading can mean you have NO chlorine **OR** it can mean you have more than 10 ppm of chlorine. So, until you get a HTH 6-way OR a K-2006 DPD-FAS kit OR a K-2006 PLUS the Taylor 1515 DPD-FAS single function test . . . you do not have a good kit.

There are a very few other kits that have the DPD-FAS test, but they are not widely available.

I got the HTH 6-way.

Ok. with TA=100 and CH=300, be careful if you are using cal hypo. If you add it directly to the pool, you are likely to make the pool very cloudy.

You probably want your pH at the lower end of the acceptable range.
