Seeking advice for water testing with ColorQ Pro and ePool

[PoolDoc]

Yes, I'd be interested in the ColorQ, since I'd rather not buy one for full price, but I'd like to get my hands on one, since they are being sold more and more widely. Email me at [email protected]. Perhaps I can swap you a new K2006C for your ColorQ.

I've done a bit more checking, and the ColorQ is not too bad, in some respects. Apparently, it's faster than using the K2006, and the FC /CC are accurate within the limited range (0 - 5 ppm). PH is reportedly as accurate as the K2006 and the TA is nearly as accurate. The calcium test is apparently finicky and problematic. Readings over 300(?) are suspect. CYA results are erratic.

Regarding Lamotte's "the sample change" -- that's possible. But they should have warned you of that up front. Calcium and CYA levels should not have been affected. Alkalinity levels should have been stable if the sample wasn't overheated, AND if they left no air space in the bottle. PH would have changed if the alkalinity did, but might not have been stable in any case. Trying to come up with a chlorine sample that would be stable in transit -- without refrigeration -- is hard.

PoolDoc is exactly on the money concerning the ColorQ and the LaMotte Waterlink Express professional water testing stations have similar limitations (I used to use the system). When you convert a titration test to a colormetric test you limit its range and sensitivity, even with a meter to read the sample. I had converstions with LaMotte tech support when the system first came out and was told that for a $100 meter it's not bad but is is a $100 meter!
