Both have been calibrated to 0.
Meter #1: ATC 100
Meter #2: RHS-10 ATC
Both are excellent refractometers.
I tested two batch's of water and the readings surprised me:
First batch,
ATC 100: .030
RHS-10 ATC: .024
Second batch:
ATC 100: .026
RHS -10 ATC: .026
I triple checked and made sure the meter was cleaned each time. Same readings.
Any ideas why?
BTW batch two is fresh water is almost mixed and ready to go into the tank.I'm just gonna drop it a couple points.
Batch 1 comes from a nano tank with fish in it already. The blenny has been sitting in one spot all day, and looks pale. Usually he is extremely lively...but today seemed depressed. That's what got me testing with multiple meters. I was concerned my dad had poor water. At first I was positive...but after testing the emergency water....now I'm confused, since they both read .026. His tank is mixed according the RHS-10 ATC, and I keep the other for my tank. My tank reads .025 and all my livestock are happy.
