Just bought a home it has a 3500 gal pool made out of fiberglass, the pump isn't marked but there is flow meter showing 40GPM the water goes into a 80sq ft cartridge filter then a 80 watt UV filter that's it.
I cleaned the pool changed to water washed out the cartridge and cleaned the UV sleeves.
in 2-3 days the green shows up, clean it up and it comes back.
The folks that sold us the house he said he never used chlorine, the pool is too small, the UV takes care of everything.
It is set to run 24/7
So much for that BS.
So I guess I need to add chlorine or the saltwater chlorine, but it appears that they don't make a saltwater generator small enough for this pool.
I know from neighbors that the source water is hard they say it 8 or 9 on some sort of scale.
So I need some suggestions on where to start and what my options may be.
Thanks in advance
