Yes there is a liner....pool is above ground 27' round...48" deep.

The Pool Calculator says to drain 68% of my water to lower my CYA from 95 to 30.

Right now I'm at about 50% full and still draining.....should have her down where I want later today.

Tonight I plan on adding 6 jugs of bleach while filling from two different wells AND keeping the small pump recirculating all night. Hopefully this will give me a quick upper hand on the algae and biomass that is left after raking the heck out of the bottom.

I should have it full maybe by Saturday sometime and running on main pump and filter.

I have been taking pictures along the way and will try posting them later.
