Well, unfortunately my 500g aquarium project has come to a virtual halt. But looking at my other options, I was planning on making an outdoor elevated pond. I would make a wooden box frame approximately 10x5x3 ft, then line it with pond lining. The catch is, if possible, I would like to make viewing windows. I have never undertaken an outdoor project like this, and am asking for some help. What filtration should a pond have? It will be a RTC, TSN, Arowana, south american tank (this is still up in the air). Pretty much filtration is my biggest concern, cause i have never made a sump for a tank like this. I would like something simple. It doesn't have to be pretty, just functional. Keep in mind that I am an experienced carpenter, and can work with tools. Just help on filtration and how to make the viewing windows.
