I'll have to disagree with you Cecil. That's a wheelbarrow Over Full !
I think that is what I have a start of in my pond. It is the only reason I still have some FH's left. They hide in it. Your opinion .. should I get rid of it?
Just a start in my small ponds too! In my 1/10th acre trout pond I can easily remove 30 wheelbarrows of this stuff twice a year!
IMHO is you will NEVER get rid of it totally. I remove mine because it decomposes and builds up, and could eventually fill in the pond over a period of a few years. I also am concerned that it will raise the temp of the trout pond a little as it creates shallow water along the edges by filling in space. And if it is really prolific(which it is in my trout pond) it could use more oxygen at night than it produces during the day?
I have also found if it is really dense when fish out time comes, the large trout will sometimes go down into it and break off.
