Red Sea reading

What would be my level for mg? I filled it up exactly to 0.9. I don’t understand how to read it.

If you read off the syringe as is, you used 0.75 of the titrant so your reading is 1500

Is that a good amount?

It’s a bit high, I like to keep mine around 1300-1350.
when you use the syringe, note that there will be some air up top. As long as the bottom flat part of the black plunger is at 1ml you are good to go. You just read where it ends up, per your picture that was around 0.25 which equals 0.75ml used. Hope that makes sense

You filled the syringe to 0.9? I wonder why they use syringes marked this way, seems very odd. If so you’ve used 0.65mls which is 1300ppm, perfect.

.9 is the max it lets me to fill it.

I would try with a different test like salifert
