Hey guys, just restarted our marine tank after the last one cracked and broke. I have a hydrometer to check salinity which I thought was ok. A good friend lent me his refractometer which shows my salinity at 1.029. I have a starfish, snails, goby, hermit and 2 clowns. how do I reduce the salinity without affecting the inverts and fish and what are the right parameters ?
