PS233 test kit and CYA test question

[mshumack]

I'm still confused. Not about whether to add the water or reagent first but as to how much of each.

The first line on the bottle says "pool water fill line". That would mean add 15ml of pool water first.

The second line says "CYA reagent fill line". That would mean add 30ml of reagent.

Is this correct? The instructions on the test kit lid says "add 15ml of CYA Reagent ..." then fill to top with pool water".

One method is 1/3 water. The other way is 1/3 reagent. Which is it?

Sorry if I'm dense on this - I want to make sure I understand correctly.
Thanks

You're thinking too much.
Fill up to the first line with pool water.
Add CYA reagent until level of liquid (H2O+reagent) gets to top line.
Shake then wait at least 30 seconds.
Fill CYA test tube at waist level until black dot completely disappears while looking in from the top.
It seems that you were doing it correctly in the begining. You may not have any CYA. What was it last year when you closed?

Equal parts of pool water and cya reagent.

Correct!

The second line says "CYA reagent fill line". That would mean add 30ml of reagent.
No, you already have 15 ml of pool water in the bottle. If you now fill the bottle to the second line with reagent you will be adding 15 ml of reagent for a total of 30 ml liquid in the bottle!

One method is 1/2 water. The other way is 1/2 reagent. they are exactly the same.

Hope this clears it up for you!

Thanks. I did not realize that it was an equal mixture of reagent and water.

sorry to beat this dead horse, but the directions on the box of the ps223 are wrong? this confused me too.

It does say
fill R013 reagent to 15ml mark----first line in the bottle.
"Step two says to fill the bottle to the neck (just below cap threads) with pool water."
It makes no mention of the 2nd line that says fill with pool water.


So do I follow the box or what i'm reading here and dothe 1/2-1/2?

[waterbear]

fill to the second fill line.
