It is almost the end of June & our above ground pool hasn’t been opened up for the summer. Mainly because the pool water is green!!! We have used pool shock (liquid) but all it did was turn the water a lighter shade of green. Please help! dian


Once you have established algae (probably the cause of your green water), chlorine shock alone may not be the best approach. There are chemicals specifically formulated to treat algae, often with the aid of chlorine shock. Certain algaecides actually target green algae as may be evident by their name. Try using one of these algaecides in conjunction with your pool shock and you will see much better results clearing up the water much more quickly.
