Hi, I was having something funky happening in my tank but all my parameters read as they normally do. I took a sample to my LFS and their Ca and Alk readings were very different than mine.
Me - Ca 460 Alk 8.0
Them - Ca 350 Alk 6.0
Then I took a water sample (same water) to another LFS.
Them - Ca 250 Alk 2
What the heck?! Obviously the 2nd LFS is a crappy one (I never go there but it's the only other one in town)
Is there a reference solution to use on the checkers to see what it actually reads?
Thanks
