Hard to believe Leslie's can be so far off -

With the education I've received on this forum I've taken control of my pool chemistry. Bought the Taylor 2006k kit and love it! But I was in a store right beside Leslie's today so decided to let them test my water to see how close (or far off) they might be. Wow, results below-

Test My results Leslie's
pH 7.4. 7.4. Got that right!
FC. 12.5. 3
CH. 160. 720
CYA. 100. 50
TA. 80. 120
PhospHates. Don't test. 500

I know my numbers are right. I've been regularly testing every day or two for the past two weeks.

And of course they told me I needed to add their Phosfree product to get those really high phosphates down.

And partially drain my pool to get the CH down. Didn't tell them I did a full drain and refill in January. CH hasn't been above 200 since.

It's the same here in Aus, I occasionally check on a couple of pools that normally rely on pool shop testing. The worst parameter is salt; one result I've seen was out by 2000ppm, enough to do damage to a SWCG if you were to believe them and add way too much salt. They all use a very fancy meter but unfortunately don't know how to use or calibrate it. CH is another one they always measure too high; they test total hardness but tell their customers they have measured calcium hardness.

We see it time and time again year after year. I wonder how many thousands of posts there are on TFP proving that pool stores and test strips are not accurate. This is why we are so adamant about buying a good test kit and testing your own water. Thanks for helping to show it once again. :)

The pH test is not accurate when FC is above 10 ppm.

I'm keeping my FC that high because of my high CYA. I used the Pool Math calculator and it said to keep FC between 11-13.

Didn't know about pH not being accurate at that range. Does it show high or low?
