We did not get our pool covered after we dropped the water line below the intake. Needless to say alot of leaves fell in before we covered. When the cover was removed the water was clear and pretty. We raised the water to the appropiate level. I checked the ph and adjusted to the correct level and turned the pump on filter.....this awful brown water was released into the pool!! I immediantly backwashed and it took several times to get it clear and then I rinsed.
The next day I could not see tbe bottom so I added the chlorine and checked ph. Ran the filter and added shock. Then I addex an algecide.The next day tbe water looked clear and I could see the bottom. I removed all the leaves with the polaris and vacuum. The liner under the leaves is beautifully blue but everywhere else is a light dingy brown and it will not brush off. Stained!
Any ideas on what happened and why that was in my sand filter and what will work to remove stains?
