ya i know what you are taking about ( some people have chicken wire and electrical fences around their ponds
).But after i lost my 2 foot koi i realy thought about it. But i found a black net that blends into my pond and you cant see it unless you are 1-2 feet away. I actouly made my own filter for 50 bucks ( but i had to buy a pump) it works great and the pond is crystel clear. Miller do you have some aquarium safe rocks that you can make a couple caves with for your fish so they can hide
. Also i just did some work on my pond and upgraded it ot a 20000 gal pond ( big jump). Do you use bamboo in your pond ( i just bought 45 stems).
