I confirmed she did use the syringe to get a precise 5ml. I had 20ml out but the tank dropped a few more dKH than I expected. So I had her get 5ml to add to the 20ml I had already prepared for her. That explains the 20.0 reading for the first one.Last time I got to the end of my Hanna reagent I was getting very off readings. My future plan is to just dump the last bit or at least use my Red Sea test to confirm.
I was going to use my Red Sea to confirm, but it expired 2/19 and the reagent in the bottle was no longer red but a pale orange. I have the one that starts blue and changes to red. Color change is very vague and gradual, not sudden or precise at all. Could have been 6 or 12...
I'm sure the tank is close to where it needs to be. I'm going to try and get my skill saw back up and running tomorrow so I can make my shelf to hold the dosing pump. I had to buy a new cable as I accidentally cut the black wire in the cord with the blade and made a terrific fireworks display for a split second until the breaker popped.
