Update.
So in hesitation of blindly adding Epsom, I was working close to upscales today and took advantage of that by taking water in for testing. Picked up some continuum mag powder to be safer. Not sure how much the 50 gal water change made a difference but they tested everything at
Alk 6.5
Cal 480
Mag 1200.
Which is way diff from what I had a day prior. I've re-tested with my kits this evening and came up with close Params to these other than cal. Smann posted that your Hanna for cal always tests at 600, which made me think. (Thank you)
I tested water from three sources tonight, make up water, display, and qt. All read 600 on the Hanna. I'm pissed. $70 for what? Bad results? I've had this thing a week. Someone's getting chewed on tomorrow!
Is it just me or is testing/ trusting a test, seem to be extremely frustrating.
I'm currently trying to still bring mag up a bit along with alk. Updates to follow.
Exodus, I've read the article before and thank you.
Mandinga , thanks for the offer, I may take you up on that soon enough.
Extra thanks for all the help from everyone. You guys rock.
