....But now that it's running I still have floating weed mats that I guess are duckweed or FA. I read duckweed has a lack of bottom aeration as cause or part of the problem. The weed is on bottom too .Fishing is very difficult and can't see fish even at noon bc of all the weed or FA.
....
I think I see a point I missed. Are you thinking that aeration will eliminate the as yet to be positively identified vegtation? IMO, that will not happen. To quote:
....Control and management for duckweed/watermeal and filamentous algae is different, but the underlying problem that caused it is the same.
(excess nutrients not being utilized by anything else in the pond)
IMO, you need to eliminate the source of the excess nutrients or introduce a more desirable vegetation to utilize them (or if the vegetation is FA you could stock tilapia if they are legal in your state). Otherwise, IMO, your options are keep mechanically removing the unwanted vegetation or periodic herbicide treatments.
At the end of the day it is your pond, your decision and your coins to spend on what you think is the best solution. I have offered all the advice I have so I will drop out of the discussion and wish you success on achieving your goals.
