evaporates and the salt stays in the tank which increases your sg
. Only add FW
to the tank to maintain your sg
level for evaporation and only add well mixed SW
(24+ hours with a PH and matching your main tanks temperature/ph/sg
) to your tank when you take out SW
during your pwc
Never add salt directly to a tank, it's caustic until thoroughly mixed and will damage your stock.
What are your current ph/sg
/temperature levels currently? Are you keeping the lights off? How are you cycling i.e. fish less/live rock?
