Hey Justin,
I'm not a pro but here's my train of thought. I remove all floating FA mats. They block the sunlight needed for phyto and zoo plankton and I see no benefit from letting them remain. I also discourage FA in spawning areas and brush piles with Cutrine. I consider it a plus otherwise and mine is always full of life. To me (right or wrong), FA is a an indicator of a healthy pond. If a pond can't grow FA, something is wrong.
Just my 1 cent
