My old (not expired) Salifert calcium test kit ran out of the CA2 bottle so I bought a new kit. The new kit is reading significantly higher than the old. My first test of the tank itself read almost to the max of the kit, at 495. I thought that was possibly because I am dialing in dosing and went overboard.
Today I mixed up a batch of new water with standard Instant Ocean and the kit read the water at 485. When I have tested freshly mixed Instant Ocean before it was always around 385. I tested a second batch of stand-by water I have for the QT tank it and also read high at 485.
I got out the old test kit and used CA1 and CA3 from it and CA2 from the new one, and the fresh water read 395. Is it possible something is wrong with the new test kit?
