Can't keep chlorine levels up

[cbednara]

or you are getting bogus ColorQ readings (it *is* a 'guess-strip' ).

Is the lamotte colorq not reputable? Here is a link to what I have. http://www.lamotte.com/component/opt.../mid,/page,19/

I wanted a test kit that used drops of reagent. Reviews were good for what I read and I liked the photometer giving me readings rather than myself eyeballing the color match.

My bad -- I was thinking of the AquaCheck strip reader. The Lamotte ColorQ is

- 3x as expensive as the K2006
+ possibly more accurate than the K2006 on pH and CYA
- probably less accurate on TA and CH
- less accurate on chlorine at low levels
- much less accurate than the K2006 at high levels (> 7 ppm)

I've asked Waterbear (who's been out with surgery) to take a look when he gets a chance. He's played with more test kits than I have. By the way, the K2006 does a titration (color change, not color match) for chlorine, TA, & CH.
