New Homeowner existing KOI pond
Hello all! I am a newbie and need some help. I just moved into a home with a Koi pond. We are debating about removing it. We have a 4 and 6 year old and are worried aboout their attraction to the edge.
We are located in NW IL
The pond has no filtration system. It is a poly lined about 2 feet with a drop off to 5 feet. It is roughly 5 feet by 8 feet. Maybe 10 larger fish 6-8 inches and 40 smaller. The previous owner left a few filter parts but cannot make sense of. There is a lot of sludge on the bottom of the pond. We are guessing the pond was not properly maintained for 6-12 months. Is this worth keeping? The fish are happy and eat like crazy.
Numerous Frogs and a few crayfish have been seen as well as a Spotted Salamander.
I guess I am really looking for feedback as well as guidance for starting out.
