UPDATE:

The rake as a bottom weed pulling device sucks! It doesn't pull enough weeds to make it worth it's cumbersome handling. HOWEVER, I then attached pool noodles to make it float and then pull it from one side to another in order to skim top weeds and algae blooms and for that it worked awesome. Of course you then have to pitch fork whatever you just pulled in on to shore.

I also rented a 250CC 3" intake trash pump to try and suck the weeds out that I pulled to shore....Did not work as planned. It was more trouble than it was worth.
