I was advised that the bottle with the reagent has a flip-top lid and a dropper underneath it. But here's an interesting point: I just used the leftovers from the JBl test, and the difference with the Salifert test is very significant. Salifert Ca - 440-450 JBl Ca - 340-350. Unbelievable!!! There is a JBl pH test that stubbornly shows pH = 7.6, even though over the past week I raised the KH from 7 to 9 (again, JBl). I connected a tube to the skimmer to draw air outside the cabinet, and it still shows 7.6. So now, think about whether to believe it or not...

I agree.

I want to make a correction in favor of JBL regarding the calcium 400 salifer, I just looked at the liquid sample instead of the piston, but still, a difference of 50 units is significant.
