Our pool is about four years old. Gunite, 16.5K gallons, Nature2. We live in southern Louisiana.
We live on a heavily-wooded lot, with a lot of pine needles falling into the pool. However, up until about a year ago, so long as I performed the proper maintenance as scheduled, I never had any algae in the pool and I never had to brush. However, over the last year or so, I am getting green algae in the corners and on some of the walls, and I now need to brush on a weekly basis.
I have always kept the skimmers and cleaner bag empty, I test the water every two weeks, I change the mineral cartridge every six months and check the chlorine tabs every week. I remove the cartridge filters and spray them out every six moths as well. My maintenance routine has not changed, so I can't figure out why I am getting algae now, after all this these years with no problems.
I know there are probably a ton of variables that could explain the issue, but I was wondering if there were some "usual suspects" when an algae problem like this suddenly appears after several years?
Thank you!
