Here are the pics of my kit. Intersting to note that I am in St. Augustine, Fl and cygnusecks is about 2 hours away in Orlando, Fl! Might be a regionally distributed kit. I think the quality control might not be very good. The first one I got had a defective Cl/pH comparator...the color bars had come unattached on the Cl side and had moved out of position and the tube was cracked so I returned it for the one I have now. Also, the Ch test is different than Taylor's. There are only 2 reagents...indicator and titrant, no calcium buffer (reagent #1 in Taylor kit)

When I clicked on Tootie's link posted above, I got an error message.

I don't know what happend????

But I'll try again

i bought the same kit last year,however I lost the instruction does anyone knwo where I can get these.I call the 1-800 number and they sent me everything but the instructions.for free....well At least I dont need to buy refills.they will send one every yr.

Tootie & Waterbear, yes, that is the exact same kit I bought in Orlando last week. According to the kit, I have balanced everything but the CH. I think the CH test in that kit is bogus. Do all of your kits tell you to put 2 drops of the "Hardness Solution A" in, and watch for a violet color to develop?

I'm gonna leave my CH alone for the time being until I get my PS234.

[waterbear]

Yes, and it does not work. Like I said before I was playing around with it and found that it worked with about 8-10 drops of the indicator and I cross checked the results with the Taylor kit I have a few times and it is pretty close that way.

[Tootie]

I' am very puzzled,when I did the test a few day's ago,it did just what it supposed too.After reading the post again this morning I did another test,and wouldn't you know, it never turned violet?????
We had a pretty good temperature drop and my water is only in the 40's,compare to the other day when it was in the 70's...
Could that be a problem with it???I' am no Expert,and really have a hard enough Time to understand all the other stuff going on in the pool...But now I' am very confuzzeld...

Ok,I had to check again before I post,and no it did not work,just like Waterbear said it took me 9 drops,and then it turned in more like a black grayish color????



@Sisie5,I have the Instructions.....

I will try to scan and post them

I don't have my kit with me so I can't post a photo, but the one I got at Walmart was an HTH (5-way I believe) test kit, not the Aqua Chem shown above. I'm also pretty sure I had to add 5 drops of the blue reagent for hardness. My pool sample did not turn blue but rather a yellow color and after a lot of drops of the second reagent it slowly turned green then sort-of blue. I re-tested on my tap water (which was not used to fill the pool) and it turned blue right away. I received the PS234 kit and that hardness test started with a third reagent - with the PS234 the hardness test worked on the pool water as expected and the hardness was pretty low. It looks like in my case there was something in the water that caused a problem with the 2-reagent test but not with the 3-reagent test (that's probably why the third reagent was added)

The Cl/pH tester in the HTH kit looks the same as the one in the PS234 kit.

. . . but the one I got at Walmart was an HTH (5-way I believe) test kit, not the Aqua Chem shown above. I'm also pretty sure I had to add 5 drops of the blue reagent for hardness.

That's the kit made by Taylor. The testblock in the OTO version *IS* the same as the one in the PS234, and the calcium reagents are the same, as well. 5 drops is the normal quantity of indicator dye for the calcium test.

But, there are (or should be) THREE reagents in that test:

1. a buffer, used first
2. an indicator dye, used second
3. the test reagent, used third. These are the drops that need to be counted carefully.

If you tried to do the test, using the dye first, and the test reagent second, you would get wierd results. But, that said, I've never heard of a yellow to blue transition on the calcium test. That transition DOES occur, on the alkalinity test, with VERY high levels of chlorine, or on PHMB pool with high levels of peroxide.
