Just ran out of calcium pro test, switched to my refill reagents and my calcium has changed from 430 to 490... Neither were expired, same test tubes and syringe used. Alk still at 7, not making alot of sense to me. Anyone else experience similar differences?
Red sea calcium refill reads much different than original kit

I gave up on Redsea because it was very inconsistent. I went with Salifert. Cheaper and it appears to be more reliable.
