This calculator takes the amount
of water in your system, your current salinity, the salinity you'd like to achieve,
and the maximum change in salinity that you are willing to risk per water change.
It returns the number of gallons and salinity of the water for each change.
The maximum salinity per change
can only be entered in ppt, this field will NOT accept SG.
When lowering the salinity, water removed should be discarded and will always
be replaced with FW (water with a SG of 1.0 or a ppt of 0)
When raising the salinity, no water should be discarded. You
should raise the salinity of the water removed to the value shown and then replace
the water into the system.
of the results do not make perfect sense to you, DO NOT use them to make changes
to your system.
