CYA Test and TF-100 - what volumes of liquids

[steve_h]

Over the years I have been through several of the little squeezy bottles in the TF-100 for CYA testing.
I have been careful to transfer any marks to the newest bottle.
I still always feel that the CYA test is subjective and want to, at least, start off right.
"Fill to the line" seems arbitrary.

What are the volumes of pool water and R-0013 which should be used for the CYA Test?
The TF-100 comes with a graduated cylinder and other measuring devices (clean syringes) can be found.

Thanks

You need a 50/50 mix of sample water and reagent. If you find you always have leftover sample mix, and you had a way to use 3 or 4 ml of each, say with a syringe, you could make your own custom batch.

Equal amounts. Typically 7 ml of each for the small indicator.

Thanks for the replies.
I will try those volumes.

For info:
It takes about 30ml to fill the TF-100 CYA tube to 20ppm mark.
There is a 14.6ml graduation on the non-FC/CC graduated cylinder.
Think I'll use the 14.6 line (X2 =29.2 ml).
So there ya go!

Thanks for the ideas

I just measured and the new tube that comes with the TF pro needs 10ml VS 30ml for the old TF100 tube. R-0013 is cheap and all, but 1/3 the supplies is 1/3 the supplies. See if you can order one.




*the googley eye still laughs at me no matter which tube I use.

Interesting.
My original TF-100 is probably from 2007 when I joined the group.
I have replaced chemicals, of course.
I agree that less volume is better, including less volume in the case.
I will investigate.

I succumb to the peer pressure.
$50 later...a smaller tube is OTW. Plus the Saltwater test kit.
Now I have to start looking for a larger case.

I have this and it is REALLY nice. I agree with the people who like the hard case on the k2006 or tackle boxes, when it is stacked with other things, but my test kit is pampered atop the closet shelf by herself.

How many did you go through before you found that one?
Brand?
Size?

Just a cheap one I grabbed at Wally World about 9 years ago. It does well for me.
