As of this moment: Total hardness 100; TC 5; FC 3; pH 6.8, Total alkalinity 120; CA 0.

I have not thrown in anything besides shock (solid and liquid). I had a pool service open the pool and I don't think they put in algaecide, but I will ask tomorrow.

Vinyl side pool, sand filter, sorry I don't know it or pump size.

I have cyanuric acid but I was going to wait until FC is stable before adding.
