How do you size a pool saltwater system?
Salt systems are rated for the maximum size pool in gallons that
they can maintain. This sizing only applies to a pool that is
barely used and does not get much debris or sunlight. In all other
pools you should go 1.5 times bigger on the salt system than the
size of the pool itself. For example a 10,000 gallon pool will
require a 15,000 gallon salt system. If the pool is used a lot or
it gets plenty of sunlight and debris, or all three you should go
twice as big.
