Koi Comets...
Not heated.
Plan to winter over with the pond, will keep a heater / bubbler in the tank.
Whatever questions you have with the pond just let me know.
As for philly... that is what like 8 hours? Ha i could almost be talked into it for a good philly cheese steak and gas money. You would have to have stuff all ready though and all the supplies. lol
I am by far no expert though and do not guarantee any of what i do. I am just a firefighter/emt who played with rocks, rubber, dirt, and water.. lol
