I've got the PB coming over tomorrow to work out the final details of our IG Vinyl pool install. I've learned a lot reading Pool School and the forums. This is a great site!
However, I'm still stumped on filter choices. I'm leaning towards a DE filter, but my #1 concern is about the safety of the backwash. Let me tell you about my setup and proposed equipment:
~18K Gallon IG Vinyl pool
SWCG - Hayward Aqua Rite
Heat Pump - AquaComfort 125K BTU
I will be backwashing onto lawn + woods (About 0.75 acre is behind the pool half wooded)
I have well water, also in the back yard
So what filter type would you get?
At first I was concerned about the SWCG and backwashing to the lawn/woods but I've now read the salt ppm is too low to harm plants, plus I have the ability to backwash to many different areas (lots of land, distribute the salt better).
However, there seems to be some concerns over the safety of DE. Its not allowed in sewers. With my setup should I not backwash DE onto my land?
