Help guess my ph .

Are you using the correct indicator solution for that comparator block? Taylor makes 2 different blocks that use different indicators. It's easy to mix them up when ordering refills. Ask me how I know.

I assume it’s right . I never order refills . I just order a new kit every year. Tf-100. I get a new kit because the makings for the amount of water added to beakers always fade away. I wish they didn’t rub off so easily
 
The "big" comparator with the CYA test in the other tube uses R-0004.

The "small" comparator with the DPD chlorine test in the other tube uses R-0014.

I think what you have in the picture is the small one.

I don’t mean to be rude but you lost me. I used the drops for the ph. I definitely didn’t use the drops for the cya
 
Taylor makes two different pH measuring blocks and they both use a different set of indicator drops.

I think you have the small one with square tubes, right?

What is the chemical number on the drops you're using in it?

Yea I think with the comparator block you're showing, the reagent used should be R-0014, not R-0004. make sure you're using the right reagent and let us know.
