What I could've done is to turn a section of my basement into one big indoor pond with a big viewing window. but too late now since the basement is already finished and don't feel like re do it all over.
if I had it my way this is how it's gonna be: 12ft long x 6ft wide x 3-4ft tall, 2ft off the floor. filtration will probably be a bead filter for mechanical and go through a chamber of bio media and plants for bio filtration and return in the form of a stream or small water fall. depends on price of the bead filter, I could use a big wet/dry to save money.
want to make the pond out of concrete so bare bottom won't look too ugly, besides I can have drain holes at the bottom instead of on the side, makes collecting waste easier.
if I want to add live plants then the back and both sides will have gutter about 6-12" wide, few inches deep, filled with substrate (sand or gravel, etc) which will be used for plants.
lighing will mostly be done by the sun since I have a window there, I could mount some mirrors to help direct sunlight to where I want. for night time viewing or whenever sun is not available I can use MHs.
