Is there anywhere locally that sells calibration fluid for refractometer? Are they all the same or are some fluids better then others. I live in Fountain.

You can used distilled water to calibrate at 0. Don't use RO/DI but distilled.

Oh OK. There's a difference? I went to seascapes and they looked at me like I'm crazy lol. I looked up the refractometer I have and it says if I use ro/di I will get a negative reading.

I have fluid. Honestly you can use distilled and adjust it just slightly below 0 and it will put you very close to actual calibration fluid. I have done it both ways.

When I use ro/di water after a calibration it registers negative.

I stopped by valley pets and they let me barrow their calibration fluid. It gave me a zero reading too. Do some calibration fluids read zero? I set mine just a hair under zero with the distilled water. My acan is dying but I'm thinking it didn't like the salt from Mr Aqua. Been doing water changes with the reef crystal salt.

My crabs, shrimp and snails all seem fine but my ric is staying small and my acan looks horrible.
