So the other day I noticed my zoas were closing up and did all my tests then tested my salinty. I do regular water changes of aprox 20%. My salinity using a refractometer is reading at 1.020. Is it better to use salt water for my top off. Or should I do a water change at a high salinity of 1.028 and see where I am from there. I dont want to stress out the fish.
Thanks
