Does anyone sell a single-reagent pool chlorine/pH test kit?
My Home Depot HDX test kit uses the following reagents: Clorine = 5 drops reagent HDX-1 pH = 1 drop reagent HDX-4 & 5 drops reagent HDX-2
My Taylor test kit uses the following reagents: Chlorine = 5 drops reagent R-0001 & 5 drops reagent R-0002 pH = 5 drops reagent R-0014
Does anyone make a Cl/pH pool test kit that is the combination of the two so that it's a single reagent for Chlorine & another single reagent for pH?
You want a pre-mix? Don't think that will happen. Perhaps a chemist can explain why.
This is a two reagent kit
Do not know the contents of this kit for pH and chlorine and other stuff but would think it took more than one strip for different tests.
BioLab
I'm looking for a test kit that has two vials for pool water, into one you place a few drops of a reagent to test Chlorine (usually turning it shades of yellow), and into the other vial you put a few drops of a reagent to test pH (usually turning it shades of red), and then comparing the color to a scale next to the vials.
Looking up BioLab, this seems to be _many_ out there

It doesn't look like he wants a pre mix whatever that is.
He just wants one chemical for testing chlorine and one other chemical for testing acidity/alkalinity.
In one kit.
This is a single reagent for chlorine and another single reagent for pH test kit that I buy locally for about half of what they charge on Amazon for the same kit so I recommend this kit but not at that price.
That's exactly what he said he does NOT want.
That's two twenty-two dollar bottles for just testing chlorine.
He said he wants ONE bottle for testing chlorine, not two.
I, and my pool maintenance engineer, both use a Poolmaster 5-way test kit.
I am a retired chemist but do not have a pool and thought I might see what is out there. There is a lot to choose from and I just picked one.
You are getting much better advice from the actual pool owners here that are familiar with the different kits.
One approach to pool maintenance is to weekly check all the chemistry yourself, which includes calculating the LSI from the temperature, pH, total alkalinity, calcium hardness, stabilizer level, total dissolved solids, and borate levels, in addition to keeping track of the chlorine, phospate, iron & copper levels.
This is a lot of work. I've done it all.
While I haven't done it, even more work than using those test-it-all test kits is to dive deeper than what the normal test kit measures, such as inorganic orthophosphates (PO4) versus the organic poly and meta phosphates (for example, condensed or compound phosphates).
The point is I've used the multi-way test kit many times. In fact, they're what I posted in the opening post.
No calculations necessary other than to figure out how much acid and chlorine to add daily to keep the pool within the test ranges.
Five drops of the yellow solution, and shake === chlorine Five drops of the red solution, and shake === pH
The trick is finding a good source of the two five dollar reagents.

For accurate pH tests, Chlorine must be below 5ppm. The reviews are correct about the Chlorine yellow colors being the same! What I'll have to do is use an old vial and calibrate it for the Chlorine. The pH colors are distinct enough to see the differences (but not the Cl).
I wonder if there are any advantages to the kits that use two reagents per test? Do you know?
