TF 100 CYA

It appear the little dropper for the CYA test takes 15ml of water and 14ml of cyanuric acid.
can you cut these amounts down equally, 7.5 & 7 respectively? Based on this amount, it should give a CYA reading of atleast 30

reason I ask is I’m almost through my entire bottle of acid for cya testing.

It is equal amounts of pool water and CYA reagent. So 7 and 7.

Well *#$¥ !!

guess my sticker is somewhat off on the dropper
so my readings have been off
Ok, good to know it’s a even 50/50 mix

The test is not meant to be precise. It is meant to be good enough for a residential pool with a cost effective method.

I’ve already dumped about 3500 gal from my pool since yesterday. So I’ll be testing everything tomorrow.
