High CYA on a newly filled pool

[aedwards1102]

We just put up and filled our pool over the last few days. If it matters, it’s 16’x48”, above ground. Before adding any chemical, we tested the water and CYA levels show to be 300 on a test strip. For what i’ve managed to find online, tap water shouldn't have CYA in it. Is it possible that something else is cause a false reading and the CYA isn't really this high?
The TA is 240
PH is 8.4
TH is 0
FAC is 0
These numbers are all from untreated, just filled tap water. I know i’ve got to get everything in range but just trying to figure out where to start.

Welcome to TFP!

You've discovered that your test strips, like all test strips, are inaccurate.

To successfully manage your pool chemistry, you will need a reliable test kit: the K-2006C from Taylor Technologies, or the TF-100 or TF-Pro from tftestkits.net (which use Taylor reagents, but provide them in more useful proportions and for slightly less money). You can read about them here: Test Kits Compared
