Thanks for the heads up, if I paid $25 for overpriced saltwater to nuke my tank I'm going to be rather frustrated...

Anyway to calibrate my calibration fluid without buying more calibration fluid?!

you can make your own using rodi water and table salt. Randy Homes-Farley has a good article with a recipe.

i am going to make a batch and buy some of the pinpoint fluid, which from my research seems to be the most reliable fluid.
