I'm posting here because I have no clue what to do about my pool. I live in the Northeast so I know the pool should be closed like yesterday but I have been dealing with a cloudy, green tint pool for awhile now. I don't want to close the pool until the water is clear. I have gone to the pool store and they say just add shock and vacuum and the pool should clear up. A month later same problem and the pool hasn't been clear. When I add shock the FC would stay at 10 for about 2 weeks without adding more. They test the water and its fine. I tested my water today and I got : pH 7.2 FC is 5 Alk 80 and stabilizer is 30-50. I use the strips. The filter runs at night for 8 hours. When I first had the problem I would run the filter for days. I backwash the filter everyday. For awhile the water would be green when I backwashed but now its clear. I vacuum the pool every other day and brush it too. I'm not sure what the problem is because when I brush the floor, you don't have to scrub, its like a dust, just mixes into the water in a cloud. But the stairs were covered in green film. I'm attaching some pics so someone can please help me.
