I am no expert. I would be thinking of pond aeration system & one ot the muck digestants/bacteria to rid & keep under control the muck in the pond.
A top predator to eat the leaches & unwanted carp. BG/LMB ?
I have considered adding a fish that would eat leeches and goldfish. Not sure what fish would fit that bill- LMB? Of course I would guess that I would still need to try to trap and remove the big goldfish. They are tough to catch! My father would be delighted if I added something fishable! I just don't want to make the fish problem worse (too many fish pooping-up the pond). Not sure how you find a hatchery that sexes their fish.
I am open to aeration suggestions. The Airmax system I like is about $1300-1400. Most affordable systems won't be able to make a dent in the approximately 300,000 gallons in the pond. I don't want to drain the pond, for a number of reasons, if I can avoid it.
BTW, the leeches are pretty big- about 5". They appear to be one of the medicinal types. We saw them on hubby and sometimes we see them swimming along the surface. We wondered if we build a float/dock and entered the water in the deep area, thereby avoiding stirring the muck and shallows, maybe we wouldn't get attacked? I guess I don't know a lot about leeches.
I would add pics of the pond and the leeches but I am new and don't know how to do so yet.
