Hi again...sorry for the late reply...not sure about the algae causing the death of the plant but can definitely cause damage to leaves...
I've experience bro algae that does rub off, but also a darker form that seems permanent - especially to lower light anubias in inappropriate exposure...
Along with the other suggestions, what's the consensus on the following:
1)Removal or pruning of coated leaves all together
3) addition of snails (then extraction through the lettuce trick or loach - if undesired)
4) uv sterilization of free floating algae (pricey though)
5) hydrogen peroxide dip + thorough rinse (outside the tank of affected plants and wood... And if able to do w/o harm to root structure)
Along with reduction of fertz and increase in water changes....
Just some thoughts until the addition of floating plants and reduction of light..

Also looked at different chem products, but most seem damaging to other plants and invertebrates (and most likely plants to boot)...

It depends on the type of algae. If this is diatoms, and it comes off easily with your fingers, then remove it or it will eventually kill the leaf. If it is a brush algae that does not come off, the leaf is probably dying; I have noticed a dfirect relationship. In my tanks with swords, the leaves that get brush algae are always dying; I don't know if the algae kills the leaf, or the algae simply attaches to a leaf that is already decaying.

I've been observing this on my valls.The leaf shows signs of decay (small spots) then the algae appears and does not usually spread very much. If it were killing the leaf I would expect it to spread more and actually kill more of the leaf progressively.

I also have leaves on the same plant die completely but they seem to decay and never develop the algae. I am assuming that the live leaf still feeds the dead zones and the algae is living off of the food supply rather than the dead leaf itself. I leave the leaves with the algae for a long time and there is typically little progression.

Yes, I would think this is probably the correct assumption (both issues). B.

would it be a good idea to trim the leaves with the algae?

Depends which algae. If diatoms, remove it from the leaves as best you can. If brush (won't come off), once you have it stopped (not increasing) and the plants show new leaves, trim off the older leaves some.

From looking at pics online i am thinking its Diatoms. It does brush off some with my finger tips. It came right off in one swipe with my aquarium brush when i had my anubius out. Is the wait for new leaves and then trim still a viable option for this kind of algae?

The "fuzzy" on the driftwood is certainly not diatoms but brush algae. This is not easy to get off plant leaves.

Diatoms is more like a film, and it easily comes off using your fingers.

ok, so assuming that it is brush algae, to get it off the drift wood i would have to remove the DW and clean it with a brush or something i take it. And for the plants just be patient and let the new leaves come in while trimming the ones with algae from time to time?
