My pool pump was not working recently and my pool went about three weeks without running. I do not close my pool for winter because, living in the south, we still like to sit outside!
When i got it to start working again, it turned a greenish/yellowish color. It's not cloudy....I can see the bottom. I thought it may be algae, so I hit it pretty hard with bleach. Nothing happened. I have a lot of trees, so leaves and acorns are always in it (I clean it every day), so I thought it may be something else.
I've tested it and double checked it with a pool place, and no metals, no algae (if there was, I killed it with Clorox)!
Hardness 145 (I know that needs to come up, but after FC comes down)
I also have air bubbles in the pool. I'm going to check o-rings on pump today.
My main concern is the color! What could it be?
