My salinity is high (1.028 -1.029) according to my new refractometer (calibrated with distilled water as instructed), the old swing arm read 1.023. Obviously I am s-l-o-w-l-y bring down the levels, but what damage can a high salt content have? How does it affect LR, Fish, Inverts? I questioned the swing arm because I was adding more salt to a volumn of water to get the correct reading that I should have been. Now it seems right for cups of salt vs gallons of water. Thanks!
