I have never added salt when topping off unless my salinity level was low I typically keep my tank at .025-.023 the lowest. My friend that thinks he know everything ( I am sure everyone know. Someonelike this) insist that every time you top off your water you need to add salt and bring the levels to. 023. So two questions one has anybody heard of doing this and what do you keep you levels at?
