I got around to testing all of my levels last night, ther were:
Alk 2.5 meq/L
PH 7.9
CA+ 500 ppm
So after a 13% water change over and adding some baking:washing soda in certain proportions I ended up with these results:
Alk 4.0 meq/L
PH 8.2-8.3
CA+ 480 ppm
I don't run a calcium reactor so what you see is what you get with my system. My question now is what are the optimal levels for ALK? I've seen mixed info about this, what is the rule of thumb?
