So I am new to the hobby and over the last 3 months I've been using a basic salt checker floaty needle thing. That thing is all over the place so I bought one of the ATC refractometers and its reading at 1.029 and I am kind of inclined to believe this is correct as I have only added salt water to the tank so far. I don't get much evaporation as its got a lid on the tank, but obviously there has been some.
So how do i decrease the salinity is it just a matter of adding RO and keep checking in small amounts? how much water do you think I would have to add to reduce it down? Its a 120L tank
