Stock tank filter and bottom drain

I will be using a 150 gal. stock tank, purchased from Tractor Supply, as my settlement chamber filter.  Here it is along with its future home.

The plan is to build a wooden platform and structure around the tank.  Doing this, and filling it full of floating plants, will make the filter system a decorative element.

I also received the bottom drain a couple of days ago - a 3" Rhino I.
