LaMotte ColorQ Water Tester

[donaldm823]

My retest with the cap on for blanking gave the same numbers, probably because I tested inside so the lighting didn't interfere much. Almost all of the numbers were off for me, including alkalinity, pH, cya, and CH.

They requested me to send them a sample of my pool water at their request. I shipped it out last Friday, but with the holiday on Wednesday I expect it will be about a week before I can provide you with an update.

So far, I have been impressed with their customer service, but I will have to request a refund if the kit can't test MY pool water.

ok-thanks for the return. I am very interested in what you find as your problem is very similar to mine.

I also found tech support excellent and they stay with you. They were able to resolve all of my issues (except the nagging doubt about CH accuracy). My other analysis were resolved by technique as the tests are very subseptible to holding the titrant bottles exactly vertical and ensuring the amount of sample is exactly at the line and ensuring no cross contamination between reagents (big fingers!!). Also my first colorQ had a bad CH reagent (something to do with the stabilizer)-which they replaced. (They reported a bad CH2 reagent lot last month). Again I was very happy with their tech support and even though by current CH results are low, they are still within the accuracy expected (+/- 20 ppm). But, before I add any calcium for my low CH, I would like to hear your resolution. As of now, I am assuming my colorQ is providing a CH result that is low by 30-40ppm.
