I know this is old but found it thru a google search. I have this smell as well. It is not offensive but it is there. I notice it when I am by the aeration or when I feed the fish and they are actively splashing the water. Is this something I should be preparing for an algae outbreak or is there something I need to be proactive about?
My pond is clear with a little FA. I also have something else starting that I will look at closer but it is stringy but tough and not slimy like FA. I will get back with more on that.
Thanks
Dave
