TF-100 Arrived Today - Have Some Questions

[h2o]

My new TF-100 arrived today and I tested the water. Now, I have a few questions about the results. First, here are the results:

FC - 2.5
CC - 0
TC - 2.5
pH - 7.7
TA - 260 (tested twice)
CH - 370
CYA - 35 (maybe 40...darn black dot)


My questions are...

a) Should I shock even though the CC is 0? According to Jason's calculator, normal FC levels should be between 3 and 7.

b) Why would my TA shoot up so quickly and is it a problem? I've had the water tested at the pool store pretty regularly and it's always been in the low 100's. Late last week I dropped the pH to about 7.2 and aerated to lower it, but I never tested it again until today.

According to the CYA / FC chart:
category/pool-school/chlorine_cya_chart_shock

you are right around the minimum FC that you should have. As for shock, with zero CC, I see no reason to shock unless there's something other than the numbers (cloudy, or discolored water for instance).

I have no idea about your TA, but that is high.

I was just reading that thread and I do think I have a bad tip. It was difficult to get the drops to come out one at a time. I would squeeze very softly and two drops would come out very quickly. I will shoot Dave an email.

Try wiping the tip with a damp cloth before you use it. Seems to be a static issue.

Thanks for the link, that helps. I would have to say my CYA was closer to 40 then.

Okay, so I went home yesterday and re-tested the TA. I wiped the tip of the R-0009 reagent with a damp paper towel before I used it and it worked perfectly. My TA was actually only 100.

Thanks for all of the responses!

Thanks for the correction, JT. I should have referred to this post by duraleigh: possible-clue-for-dropper-tip-issues-t7645.html?hilit=tips
