" Hi Jeremiah, not sure what you mean by a moving bed media filter? I am not shying away from any option, just want to keep it as simple as possible. From what I've heard the media grow bed serves as a biofilter quite well.. "

"Hey Joel, Actually, once you have them set up nicely.. tack them in so that they cannot move and I have found them to be no problem whatsoever, and easy to adjust if you need to.  Just cover the tube so as not to let light in (to stop algae)…"

"Jeff, My thinking is an angular aggregate (like crushed limestone) set to a minimum pack-able depth might work very well. While a smooth floor surface might possibly allow a more free flow of liquids on their way to the drain, the benefit of…"

" I figure something like gravel would allow water to drain through as well in the event of a spill or leak. Not sure how it would be for walking. I'll have to keep asking around."

"I like the white gravel idea.  I've been kicking around in my head ways of covering a dark surface in the summer to avoid heat absorption.  That seems like the best one yet! You could use paint with some texture in it.…"

"Jeremiah, I like the idea of dyed black concrete. I would hate sand and the resultant mess when there was moisture on the floor. I would probably be way more willing to put down an inch or so of some crushed white colored stone in the summer months.…"

"That makes sense.  The best surface for absorbing heat is something with high mass, such as concrete.  A bit of insulation with black-tinted concrete poured on top of it would absorb a lot of heat.  In summer you'd need some way…"

"Dirt gets muddy. I found that out this year. I laid some 18" tiles that I had on the ground to stay dry. Also I read somewhere that gravel will absorb heat during the day. Any kind of flooring should insulate from the ground to some extent."
