I been having some corals die off and it’s been a battle trying to figure out why.
I have a Milwaukee digital ma887 tester. I filed every direction to calibrate and test. I’ve had it for a year now that I’m looking more into it my refractometer the cheap one with light says my tanks at 1.027 the Milwaukee is showing 1.025.
my refractometer is newer and I have calibrated it. It clearly shows 1.027.
What should I believe?? The digital one or the refractometer?. Also I did buy the Milwaukee on Amazon warehouse so it was a returned unit. Maybe it is defective?
Thanks
