TF-100 OTO test

[AV8TOR]

OK my FC is 16 so that renders my OTO test useless or does it. I have read that you can add 10% pool water to 90% distilled water test and read then multiply the result by 10. Will that work with this OTO test for high TC values on a daily basis or don’t bother?

No, it won't work. The accuracy gets diluted by virtually the same amount so it renders the test almost useless. You'll need to test with your FAS/DPD test for now and then use the OTO this coming Spring (or when you get your CYA down).

OK thanks for clearing that up
