Do you happen to know what the calcium and magnesium levels of the tank?
I understand the alk level is high from the salt mix initially. I am just curious if the calcium or the mag level is low.
nah I don't have those 2 kits yet sadly. That's why I tested GH as well just to get an idea. I'm assuming that since GH is so high that calcium would have to be pretty high as well. Just a guess though.
