yesterday noticed some yellowish-green residue on the wall of the skimmer side of the pool (rest of water looked pretty blue and clear) so we gave the pool a thorough brushing and I added more chlorine at around 10 p.m. At 11 p.m. last night my FC was 6.0 and at 8 am this morning it was still 6.0 (pool is chlorinated by manual addition of liquid chlorine only, no SWG or other automation), but water still seems to have a slight greenish haze when I brush the pool. We do get a fair amount of plant-based stuff landing in the pool, including the pollen from the neighbor's pines and our own birch trees, so could I have mistaken a layer of degrading plant material for algae? (Hubby was in the pool yesterday and he thought it was algae that was starting to grow on the steps b/c it felt a bit slimy)
Here's pix from this morning - not sure if that'll help with the diagnosis since it's hard to tell the color of the water with so much of the pool in shadow. I tried to rotate two of them in photobucket but they still end up sideways so apologies if you get a stiff neck from viewing

neighbor's big pine trees - the pollen and needle factory LOL
PS: having just installed the warranty replacement of my clear solar cover, am wondering how low I should let the FC drop to before putting cover back on - I don't want to significantly shorten the life of the cover but I *do* want to keep our water temp nice and cozy so we can use the pool for something besides brushing and leaf-raking exercises!
