Pond cold water garden fish pond or koi pond. Diy , Homemeade , amateur. My journey from a small goldfish pond to at least 4000 gallons for bigger Koi Carp Fish. I plan to have 4 big big Japanese fish in there and home breed them. Worried about the 1st winter so I might bring them on doors not sure. Need a better filter. Will make one from a barrel filled with sand and gravel. Plenty how to videos on here. Learning as I go and fighting algae blooms every week. So my pond isn't balanced. I've added some plants and seems to have slowed the algae Down. Will be making my own UV filter not only for the algae but for ICH and similar diseases. Any questions feel free to ask.
