We live in South Georgia and have a pond in our backyard that is approx. 100 ft x 50 ft x 5 ft deep. Right now it has channel catfish and bream. We have dug a canal from corner of this pond that is about 12 ft x 3 ft x 3 ft deep and have a bridge over this stream. There is mesh wire under the bridge to be bottom of the stream so that the catfish/bream cannot get into the canal. We pump well water into the pond via a fountain head a few times a week to keep it full. We want to put goldfish and koi into the canal. Will this work? We were hoping that we could transfer the goldfish and koi into the big pond once they started to outgrow the canal. Would that be ok? The biggest catfish in the big pond are about 12 inches at most. Also, there is no type of filtration on the pond other than the fountain but we do want to build a simple waterfall (without a filtration system) at the end of the canal. What do you think of this setup and do you think it will support the goldfish and koi long term? I want them to grow big! How big do you think they will get in this type enviroment?
Thanks!

Indoor fountains that energize plant life, calm pets, and relax people are his trademark. A few of the skills necessary migh (more…)
