Ooops rickjames beat me too it!

Measured today's change water: IO mixed to 1.026 = Ca at 420. (Aquarium Pharmaceuticals test kit, fairly new.)

Calgary water is pretty hard to start with, but I'm still a little shocked.

Thanks Jack and Rick :biggrin:, and to everyone else who responded. I took my salt in today to the LFS where I bought it and they were happy to replace the pail with a newer mix of IO, as my pail was over a year old even tho it was just opened. I was told by the manager that IO does mix up low, so the info you guy's provided has been a great help.
I plan on testing the new bucket along with a bucket of Kent's salt too, and if the IO is still too low then I guess I will have to buff it or remineralize it and then switch over to Kent :confused:

Thanks :mrgreen:

Just talked to Kent and yes the salt is still being made/blended at IO. At this point they have no change over date if at all.
