Inherited pond Advice on my mom's pond
My Mom moved into a house that has a small fish pond out back. The fish seem to be active and come out to eat when she feeds them but we have never been able to see through the water because it is so dark and grimy. I have an aquarium but don't know much about ponds- my first thought was to toss in a bunch of hornwort to starve out the algae but now that I am here and seeing the pond, I think its going to take a lot more than that. AFAIK there is no filter in the pond.
This is in tennessee mountains so it freezes over in winter. The fish survive and we see them again in spring. Is there anything I can do now while visiting to start rehabilitating it?
Pictures are from when she has tried scooping out the gunk but it stirs it around.
