im in the middle of a 2x4 framed 1200 gal indoor pond and my wife already thinks im nuts. i bought my house 5 months ago and it has 2x 2000 gal outdoor ponds that came with it. that is when i started keeping fish. i have been using a 500 gal kiddie pool for the last 2 months, and i am upgrading to be able to house all the large cichlid that are at my lfs thats going out of business this week. i dream of one day doing a 5k+ aquarium, and you make it seem possible so thank you for inspiring me. (time to get back to building the frame work)
