Just got a house with a yucky pool that looked like it wasn't cleaned for years. I have read all the pool school info and removed All the leaves I could dig up and started the shocking process 2 weeks ago. The pool started out a black/ Dk green color and turned brown to a bright green to a lime green to what is now a blue green color. I can't see the bottom yet but it's clearing up deeper everyday. As it clears up I'm noticing brown stains on sides and stairs, which clears up with the vitamin C tablets. My main question is how should I proceed that would clean the pool the most efficient and cheapest way. Should I add AA now or need to wait until I can see bottom of pool, will the greenish color go away in time or do I need to treat it.
