Hi i'm new to planted aquariums and i've been noticing some algae growth but not sure if i'm suppose to do something about it?? Theres some stringy dark green growth on leaves and my shells. Think its hair algae.
Also brush algae that came with the driftwood i purchased at LFS. I tried to remove it with my fingers but couldn't get all of it. And lastly, these green dots that appear on my aquarium glass.

Am i worrying too much or it should just take care of itself?

Heres a list of plants i have that fills both tanks...i think i have alot..

Plants- Marselia, Hygrophila polysperma 'Sunset', Echinodorus parviflorus 'Tropica', Hygrophila Difformis, Hemianthus micranthemoides, Ludwigia repens, Hydrocotyle leucocephala,Heteranthera zosterifolia,Bacopa monnieri,Ludwigia inclinata var. verticillata 'Cuba', Rotala Wallichii, java moss, Xmas moss, java fern

I dose with flourish once a week and recently started excel every other day
