FYI, https://www.youtube.com/watch?v=NUW0vPxSWJs I already have two ponds. But I want to build a HUGE one! I am going to use underlayment and a heavy gauge liner. I want it big enough for Koi, Koi get pretty big, so they need a lot of room. I'll get pet quality Koi since we have hawks where I live. :smile:
He he! I think maybe I will stick with feeder goldfish. If they get eaten, it's cheap to replace them.
