CYA not showing yet.

Well I got home today and my FC was 2.5 All the other days it's been 1-1.5
CYA is still 0. Do you think the CYA is taking effect or is the FC difference just coincidence?

No expert here but your test kit from Wal-mart (I have one too) has a quirk and the Taylor might be similar. Make sure when you are testing for cya that you allow the solution to sit for a while (I let it sit 10 minutes) before putting it in the black dot tube. I lost a lot of stabilizer reagent before I realized the recommended 2 minutes was not adequate. This may not be your problem but I had a similar experience as you before being a little more patient with the test. Hope this helps.

I'll give waiting longer for the solution to develop a try tonight. Taylor's instructions say to wait 30 seconds. I noticed my afternoon CL reading was higher yesterday, so something inside me says the CYA is there. We'll see. I'll post tonight what happens after I wait a longer amount of time. Thanks.
