Hi:

Frankly, I think you are asking the WRONG question, dangerously wrong for your health and your husband's. The question I think you should be asking is:

"Why is my pool green and what can I do to prevent it, so it stays clear, clean and sanitary?"

IOW, your pool is probably infested with algae, and the algae's presence means you don't have sufficient chlorine to sanitize your pool, kill all the nasty, dangerous bacteria that can make you very, very sick or worse. Algae is the canary in the coal mine warning of unsafe bacteria in your pool.

But if your green is not from algae, then it's from excessive metals, mostly copper, in your water and that needs to be addressed as well.

Trying to filter this stuff out is about as effective as spraying deodorant on dog droppings.
