I am in the process of converting the 4x4 feet frag tank into a top view tank. I am enjoying to watch my giant hippo tang from top down. It is like a blue koi.
Okay, done some searching and pong a running saltwater pond in FL installed by Wet Work. It's running but no livestock yet but I think they're close to it.
Info on the project.

With the running waterfall, I wonder how much evaporation per day they're seeing.
