Backwashing and shocking

[waterbear]

You have a K-1005, which you can get directly from Taylor for $39.05 plus shipping. It is ok but for just a bit more money you could have had a much better test kit.

The TA, CH, and CYA tests are the same as in the K-2006 so they are what you want to have.

The pH test is not as precise as the one in the K-2005/K-2006 but usable. It is better than most other pH tests, FWIW.

Be aware that this kit uses pH reagent R-0014 and NOT R-0004 when you need to get a refill. The acid and base demand tests in this kit are not that trustworthy. The K-2005/K-2006 is much better at these tests.

The chlorine test is a DPD test and your comparator does not have the dilution markings on it that the K-2005 kit has so you would have to do the dilutions in a different container first.

I would still add a stand alone FAS-DPD test to this kit as Polyvue mentioned in his post above. This will give you the functional equivalent of the K-2006, which is the kit most recommended here and on other forums. The advantage of FAS-DPD testing over DPD testing is that you can test up to 50 ppm FC with a precision of either .5 ppm or .2 ppm. There are no dilutions involved and there is no color matching. It is a drop counting test that turns from pink to colorless and it basically foolproof. It is a bit slower and slightly more expensive per test but its advantages far outweigh its disadvantages. This would have you all set as far as water testing goes!

Hope this info is helpful.

Thanks Waterbear!
Your information has been very helpful and informative. I have a much greater respect for my pool.
I am going to get the FAS-DPD. I'm very interested in just what "precise" looks like.
Thanks again to everyone.
