Fail.

Softened water will actually damage the pool surface -- plaster.

Best I can tell.

An RO for 30,000 gallon pool? Please? Cost for a softener, add that up
real fast.


Umm... Not a fail... You are perhaps only familiar with the sodium
water softeners, there are other types out there which can be used
with other salts that cost more money...

If your pool's plaster is so fragile that a little bit of salt in the
water
(which there wouldn't BE if the OP softened the water and then
filtered it with an RO system) then the acid in the rain water must
really do a number on it...

The reason you shouldn't use sw in a swimming pool is sw leaches minerals
which destroys plaster. If the OP has a vinyl pool then it may not matter.
The reason you don't use RO is RO systems use water to make pure water. Mine
uses 4 gal for every gal of filtered water. Not practical for swimming
pools. You want the minerals in the water, particularly calcium, to keep
the plaster healthy. That's why I suggested periodic floc. Or maybe the sand
in the OP's filter needs replacing. There is specialized sand for cleaning
finer particles, or maybe the sand in his filter is just old. It's supposed
to be changed every 4-5 years.
