All the leaves get covered in this black algae and I don't know what to do with it anymore. I tried to trim it and treat with flourish excel but nothing works. I run co2 and have moderate light with dual t5 regular and the tank is 46 gallons. Is there anyway to get read of it?

Less light. I see in your second picture several leaves that don't have the algae- and they are shaded by other leaves. My suggestion is put a piece of window screen or clear plastic just over the area of anubias to cut some light, see if it helps before making a permanent change to your lighting.

Bump: Mine had similar appearance- until I cut back a little on the photoperiod and got some floaters. See the newest leaf on the left didn't have the black algae. I was never able to remove it from the older afflicted leaves so gradually just cut them off as new foliage grew in.
