A pool with a poor quality of water has probably caused the greenish colour, it is inadvisable to swim in the pool until the problem is rectified due to possible heath issues. The green colour may have come from and algae build up. To solve the problem a through clean of the whole pool as well as changing the water is probably necessary. To prevent this happening again there are chemicals that should be added to the water at regular intervals to kill bacteria and other unwanted creatures. It would be best to contact a specialist dealer in such things to get a second opinion.

You have to treat pool water with pool chemicals and use a pool filter to get and keep the water clear.
The color of the pool is no problem at all. If the water is green, who in his right mind would jump in?
It is not the salt water pool or the salt water that is turning your hair green. It is a poorly maintained pool with a chemical imbalance - pH and total alkalinity out of required parameters.
I am not sure why this has not been answered. The most common reason for the green is algae growth. If you put on a solar cover and ignore pool maintenance, then the algae will grow as the water heats and when you remove the cover, the pool will be green
You must first determine the cause of the green water - then rectify that. The green water could be the result of the equipment not functioning correctly, or not being operated correctly, or being undersized for your pool. Or it could be a water balance problem.
Your pool water may have turned green even after adding Fresh and Clear because of metals in your water. It is likely copper that is causing the water green. Your pool store will have products available to remove the metals and clear your water up. You might also have algae if you are not putting enough chlorine in the pool.
Green pool water is caused by algae. To remove the algae, bring the pH level of the water to 7.8, scrub the sides and bottom of the pool, shock the water with chlorine, then vacuum up all the dead algae.
Shock it. Sold at Walmart, Lowes, or possibly your grocery store.
The pool water is green because of algae- which is a type of plant. You just need to add more chlorine to kill off the algae...
3800 gals of pool water shock it with 1 gal bleach
Hair bleaches in the pool not because of the chlorine, but because of the metals and copper in the water. If the pool has a high concentration of metals and copper, then yes, it will appear or turn a faint green.
