Why does the water in my above ground POOL keep turning GREEN I'm constantly cleaning it & adding chemicals?

Question

15 feet by 42 inches tall

Answer 1

its probably envious on the pool next door

Answer 2

Get a water analysis done right away.  If the Ph is not right, it doesn't matter how much chemical you put in it, it won't be fully effective.  And follow the instructions to a T!  

Also, is anyone swimming in your pool after being in the lake?  That's a sure fire way to get algae.

Answer 3

Ha! I love the envy answer.

I have recently seen the same problem in an apartment pool. Its pretty big, maybe 20x60, and on weekends it turns green literally overnight. During the week, they have pool guys always adding chemicals and it looks pretty nice. Now I have a theory, but it sounds bad, so I will keep it hypothetical.

Hypothetically speaking, if your neighborhood has a couple of teams of landscapers that like to use the pool as their own personal bathtub after a hard day out in 100 plus degrees, can that make the water go green?

... I'm just askin'

Answer 4

You must live in an area of high temperatures to create algae. You will have to give it what is known as a "shock treatment" this is where you over load it with chlorine powder so this way you can spread it around the pool. Check and see it there is a pool supply place in your area, take a sample of the water (large) there and have them analyze it for how much to use and further instructions. Also figure out how much water or the size of the pool.

Answer 5

put in algacide about 1/2 bottle then get your ph right then chorine level right and then add chlorine stabilizer
