Magnesium Mystery

When we tested the water in our tanks at the meeting, my 90 gallon was at 1350. I tested tonight and it was 1500. I havent done anything to the tank since the meeting, not even top off. I tested twice and I tested my 20 gallon just to see if the test was messed up. my other tank is at 1340. Whats the deal?

Probably the difference in test kits, just my best guess

I use the same test kit as the meeting. Its Salifert

Same brand-- not the same kit
