You wouldn't think the height would matter, I've just been on this for a while and ruled damn near everything out.
I run RO (12ppm base) with Cal/mag- started off with 150ppm as a basis and I had gotten spots.
So I up'd it to 180 and the same thing, if not worse.
Now I have taken it back to 100ppm and the problems persist, not as severe- but there.
Just wanted to catch an idea of what others are putting in their water (CalMag wise) when runnin similar setups
-ml/gal.
-ppm
How much does ever body use in your rig?
