i have a 10k gallon ingroundpool, vinyl liner, just before spring the pool cover got blow off some and all stuff on top went into the pool, i finally got pool clean and chemicals balanced outside of chlorine being high but is dropping to normal levels slowly, shocked pool twice, but problem i have is cant get water at bottom of deep end completely clear, u can see bottom of pool fine but still has a slight green tint to it, shallow end is perfectly clear, there is no bottom drain to the pool, just one skimmer and one returns on opposite ends of same wall, has a sand filter and sand was replaced this year, pretty much what im asking is how do i circulate the water at bottom of deep end enough so that it gets sucked into the skimmer and filtered with only one return on opposite end? This is first year living at this house, pool is 25 years old, but new liner put in 2 years ago
