When a pool turns green, the cause is the build up of algae. To remove the algae, chemicals will need to be bought to restore the PH levels in the pool, killing the algae.
Drain your pool, then scrub the walls and floor with pool cleaner.
By killing the green algae with an algaecide available at your pool shop.
The pool turned green in Rio due to an imbalance in the pool's chemicals, specifically the pH levels, which caused algae to grow and give the water a green tint.

My pool looks fine, thanks.

Shock the pool with chlorine (your Pool shop will tell you how much to add). Run the filter constantly, cleaning as necessary, for a couple of days. Brush pool walls as well. Then install a salt water system and you won't get that algae coming back.
The sand filter wont make a pool green this happens a s a result of algae.
There is no difference, covered or uncovered, a covered pool is only going to keep the debri out or on top of the cover, where an uncovered pool is going to collect all the debri on the bottom of the pool its sometimes more work depending on where the pool is located, you may or may not have to scrub the walls and floor, The only problem I know of would be when the short burst or warm weather comes your water will turn green a lot faster without a cover, There is no difference, covered or uncovered, a covered pool is only going to keep the debri out or on top of the cover, where an uncovered pool is going to collect all the debri on the bottom of the pool its sometimes more work depending on where the pool is located, you may or may not have to scrub the walls and floor, The only problem I know of would be when the short burst or warm weather comes your water will turn green a lot faster without a cover,

The only reason the pool would turn green would be if the Baquacil is not entirely out of the pool and it reacts with the Chlorine.
The color of the pool is no problem at all. If the water is green, who in his right mind would jump in?
