I'm moving from Pennsylvania to Denver C. O. I plan on setting up a what I would call an easy clean up pond. In a nutshell I plan on popping up the 100g lagoona Wade pool and framing it, putting in a heater and have it run off of bubble filters. I currently have this setup back home but I'm worried about keeping it cool during the summer. Some side information is this setup if for exotic goldfish not koi.
