New Taylor K 2006/CYA test

[morojo]

Got a Taylor K2006 test kit. Having trouble with CYA test. Pool store says cya level is good but the taylor test doesn't seem to read any, water won't go cloudy at all. What might be the trouble?? Other test results follow

fc - 3.5
cc - 0
TA - 90
ph - 7.5
calcium - 250

Have you seen this link?

Did you follow the instructions to the letter?

Did the pool store tell you a specific result or just said it was "ok"?

While not always 100%, we almost always trust our own results rather than the pool store. They (pool store) can be wildly innaccurate......not infrequently on CYA. My bet is you have none in your pool.

Yeah well I recently added about 1/2kg of stabilizer to a 58000 litre pool so I would think there should be some or can it dissappear??

When did you add it?

How did you add it?

Was it liquid or granular? Granular can take up to a week to dissolve and fully register on tests and if my conversion/math is correct, 1/2 kg for your size pool is not very much at all, and likely won't register in a Taylor test tube, because the measures start at 30ppm.


Please take a moment to add your pool equipment/specs to your signature. Go to User Control Panel, then Profile, then Edit Signature.

Added 5 days ago, granular in a nylon stocking put in the skimmer. All dissolved on Sunday.

Hey morojo,

What is your water temp?

Well, with a cart it's unlikely you backwashed....my assumption is that you didn't add enough for your pool size, to register on the Taylor view tube. Was your target 30ppm? I would go ahead and add another dose targeting another 20ppm and see where you end up in a week. 48 hours after it's dissolved you can increase your FC levels accordingly, right now I'd assume you have at least 20, and use the chart for the appropriate FC levels.

Temp at cya test was 78, goes down to about 71 by the am

My redneck math may be completely screwed up here but near as I can cipher, 1/2kg of CYA in a 58000l pool would result in a CYA of 10....(undetectable)

I also get about 10 CYA.

I knew it was low, I wasn't sure how low....the conversion to kg stuff throws me off....

Adding 1/2kg of stabilizer to a 58000 litre pool will raise CYA by about 9. Since the test treats any level below 20 as if it was zero, getting a test result of zero is to be expected.
