Thx


That stuff is there most likely because you have an excessive amount of nutrients in there causing it to flourish. Reduce the nutrients and reduce the scum.

And the alum treatment will reduce nutrients? I did not know that.
I shut off the feeder a few weeks ago. Hopefully that will help. I guess my original question as to if aeration will help is still unknown. I think I’ll just wait it out, if the Cutrine plus does not help. I can’t see giving Rex another $2500 on a most likely solution. I wonder if it has anything to do with the American pond weed? I have a lot of it now, and I’ve never had the scum before.
Thanks for the replies esshup. I must have a very unusual problem, as the solution seems fairly elusive.


9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
