In-Tank Fluidized Sand Filter?
We took our son to a children's aquarium the other day, and in one of the tanks I saw an area where sand was "bubbling" up an inch or so before falling back to the bottom. At first I thought some critter was digging in it, but quickly realized it was just a water return under the sand.
In addition to being a visually interesting "spring" effect, I've started thinking this might actually have some functional effect as a fluidized sand filter.
I was thinking that if I created an appropriately sized area of course, plain sand, segregated it in some fashion and piped the output of a small pump down into it with an upturned nozzle, I might get some measure of the benefits of an FSF without actually building and installing a discrete unit. Plus, of course, an extra bit of visual interest, and maybe a way to deal with a dead spot, if thoughtfully placed. I figure it wouldn't hurt anything, at minimum. :shrug:
What do y'all think? Am I smokin' crack on this, or am I maybe onto something?
