    HELP URGENT please - salimity

    So i set up my Nano tank and have fish in it 2 clowns who seem happy. Started with atm colony for bacteria. my red sea refractometer out of the box ive mixed to 35ppt i just got a hanna salinity checker - calibrated (twice because of reading) and its coming out at 46ppt !!! What do i do. Which do i read as true. Im terrified i lose the fish. cant get to a fish shop to have water tested by them till monday now.
  2. Open but never used! Poseidon Salinity Pen Plus, Never used. Includes calibration liquid. Retails for $70 Tunze Silence 1073.020 630 GPH pump. Retails for $90 Looking to sell both for $80 shipped within US. Message with questions, Thanks!
  3. Received my new toy today and I'm a little worried about it's accuracy. The digital pocket tester says the SG in my tank and in my saltwater reservoir is 1.021. My calibrated ATC refractometer says 1.025! From what I've seen and read, I don't believe there's a way to calibrate the digital pocket tester. I know optical refractometers aren't the most accurate, but I didn't think it would be that far off! Wouldn't I see issues in my tank if the SG is that low?! http://www.coralvue.com/salinity-temperature-digital-pocket-tester
