Your pond looks awesome keep up the good work

A friend of mine has a koi pond that is scaled in depth from 2 feet to 8 feet deep 14 long 6 wide looks awesome but he doesn't winter his fish outside due to extreme weather in winter he has a 1200 gallon tank in his basement where the koi winter I think his biggest is just shy of 26 inches long
