Hello, I have a Hanna ULR phosphorus checker
According to their conversion. 24 ppb = 0.074ppm phosphate. But online converters show 24 ppb= 0.024 ppm. Which is correct?
Also, I have a small potassium dropper bottle by aqua forest. Doesn't say what kind of potassium. In the dropper there is crystal precipitation jammed rendering the dropper useless. But there is still clear liquid in the bottle. Is the liquid potassium? And ok to use? Thank you
