He's already done such test and only one seem to be quite low in strontium:

But it seem that even people using a salt with good amount of strontium might still be low in this element, thus the use of testing.
I am using IO Reef crystal salt wich has a concentration of strontium quite high with 12ppm and yet I am always low on that element.
Only the Royal Nature salt seem to be really low on strontium, all others seem to be fine and also the second batch of Royal nature he tested had much higher level of strontium near 10ppm.

Daniella, if you can, see if he can test some of your freshly mixed water before a water change. I'd be curious to know if the Sr levels are already low in your salt mix, which would give you consistently low readings. We might be able to pinpoint what is using it the most.
