Advise needed......

Hi everyone

I've passed the OCLT a couple days ago. My pool water looks as clear as it can get( Thank you for the advises that was given from here ). But I always noticed that there's some black stuff build up at the bottom of the pool if I do not vacuum daily. Is that normal?? Or I still have Algae somewhere?? I've cleaned my filter twice ever since my water turned clear from the opening day ( 11 days ago ). I guess my questions would be 1) Do I still have Algae living in my pool?
2) Do I need new cartridges for my filter?

PS. I'll try to upload another photo... But it just won't let me, always disappears when uploads hit 96% ( Not sure why?? )

Thank you in advance!!

If you passed all three criteria to end your SLAM, I would be inclined to think that you are just battling the environment. How's your FC demand?

I know that all my patio furniture is covered in a layer of dust and pollen, it could be that as well.

Are those pictures after you cleaned the cartridges?

Thanks for your replied. Yes. Those pictures were taken after I washed them with a normal garden hose. And I also have a lot of dust on my patio furniture as well. And also across the street from my backyard fence, that neighbor's house is building a pool as well. ( on & off construction since last October and still ongoing.... )
I have not tested the water since I passed the OCLT. I'll do so today. Because It's been raining non-stop lately...http://s1149.photobucket.com/user/alnfong/media/DSC_1756.jpg.html

Rain washes the dust and dirt out of the air....right into your pool! It dilutes the chemistry and dumps dirt to the bottom. Vac and test, dose as required.
