I bought a second hand Hannah salinity checker and the readings varied when I was mixing, then it seemed to go up again. It was displaying 1.025 yesterday. Today I tested and it showed 1.028 so I was panicking and checked using a traditional refractometer which showed between 1.020/1.021. I tried to calibrate the hanna but it kept saying error. I tried it anyway and it said 1.020.
Is this too low?. The issue I’m having is I started a cycle yesterday using atm colony and there is a slight trace of ammonia but no nitrates or nitrites. One of the clown fish is swimming at the top of the water line. So if I have to add more salt water that will be a water change and reset the cycle etc
