Hi all! New to this site and new to pool ownership! We bought a house with a 25,000 gallon in ground pool back in December. It was not properly cared for to say the least. Needed to replace both the pump and the sand filter! We finally got everything under control, but I'm noticing every 2 weeks or so, the water becomes slightly cloudy with a blue green tint. The floor and sides of the pool get a yellow/brown/greenish color film on them. I notice that when I shock it (I add 2lbs of power powder) it goes away, pool looks beautiful, but then as the chlorine levels come down it comes back!
What am I doing wrong?!? Do I have algae? Right now the chemical levels are all balanced but the pool still has this slight cloudiness and blue/green color. I have attached 2 pictures one of the deep end and one of the shallow for reference.
