Over this past summer I was getting constant algae growth in my pool.
I couldn't understand why. The algae would appear every day. My chemical levels were correct, i had my auto cleaner in there, but it would still bloom.
Since my brand new liner is getting replaced today (stupid deer) I decided now is the best time to clean my filter out before winter.
Especially since i didn't want all that old stuff in the filter going through the fresh water in the pool.
Well when i opened up the filter, my first thought was...That's where my Algae problem is coming from.
So after a couple hours of taking the filters out and hosing stuff off my filter now looks like this.
With that being said, especially to new members like myself, you might want to check your filters if you are constantly getting algae blooms.
