Black stuff growing on plants

Hey all, I’m really new to this. Have a really small tank (2.5g) and have a really nice Anuba? I have no idea what the water parameters are but it’s crystal clear, I do regular changes using only rain water which has been tested by the shop to be very pure (with some salts added) and have a successful shrimp colony growing so I figure it must be OK. Why is this black stuff growing and why is my plant looking so sick? What can I do about it?

Oh, I should add that the black stuff is predominantly on one side - which side was receiving direct sunlight for a month (next to a east-facing window). But that does’t fully account for the other issues the plant seems to have developed.

I used flourish excel double dose on everyday along with my regular Co2, for 5 days. Almost all BBA eradicated. Did a 40% wc also. Added SAE 2 now but I didn’t find them eating the BBA. They are waiting for my regular fish food LOL. Importantly reduced the food also.

You can dip the entire plant in a 1:19 bleach/water solution for 1-2 minutes then wash it off thoroughly. Should take care of the current algae.
I'd try to find a shadier spot for your anubias since excess light is probably the culprit
