1st test results

Aggie97,

You are ABSOLUTELY correct. Time and again, I see those results being "corrected" when there was no error.

For new users, it is easy (almost likely) to assume that you should post values for both the FAS/DPD and OTO tests.....which is exactly what you did.

After a while, we all figure out that they are seperate tests for different reasons.

Aggie, most of us simply post the results for the FC and CC (from the FAS/DPD test) and let everyone do their own math. However, I knew exactly what you meant and it happens on this forum so frequently it should be apparent to all of us.

Aggie, Dave:

The OTO test kit in the PS-233 and 234 is for quick testing and pH. Use it instead of the FAS-DPD test for your own testing to let you know if there's a problem or you're OK, but it's pointless to use it for posting your test results--just adds to the confusion--just FC and CC are necessary anyway. TC is for only one number or when you have FC and TC to compute CC. When using Ben's kit, I suggest you use either OTO for TC, or FAS-DPD for FC and CC, but not both.

I use the PS-200 for a quick test when I'm in a rush. But if I need to ask "What's going on in my pool?" I'll only use the pH test and take the FAS-DPD test.
