We bought a house in Oct.2013 and it came with a pool.Spent a fortune on it last year and never got it right.New pump and new sand this year and still not right.Had water tested and did what was required....didn't work,water was still green and no chlorine.So we tested again and they said we need 27 bags of shock to correct this problem "No Free Chlorine" well we put the shock in last night and at least the water is not green anymore,well with $120.00 worth of shock I guess it should be.But the water is still not clear and therefore we can not see to vacuum pool.So now whats next.Any helpful information would be greatly appreciated,since we are running out of money to throw at this.Thanks
