So, it sounds like you are suggesting removing the algae, rather than letting it decay. This would mean raking (ugh) or Tilapia, correct?
Yes, raking the FA is definitely an (ugh) job. You can't even just rake it onto the shore rocks or the surrounding bank. If you only do that, the subsequent rains will just wash the nutrients from the decaying FA back into the pond.
You can definitely make improvements by adding beneficial plants. They should be easy to establish in your pond bottom material.
What plants do you like in your area ponds and lakes? Maybe identify those, and then post on the forum to see if they are invasive, or if usually considered beneficial.
Do you have crayfish, turtles, carp, etc. in your pond. They all love to eat newly established plants. If you have those critters, then you probably need to read some of the threads on protecting your plants.
I don't know about the phosphorous binder. I believe there are also a few good threads on that. I think(?) the efficacy of that treatment is dependent upon some of the other water chemistry conditions in your pond? Never hurts to get a few baseline water quality measurements in your "pond notes" anyway.
Good luck on your pond improvements!
