Just asking, has anyone considered using a swimming pool sand filter lateral in a Skippy style barrel filter?
The irrigation tubing or 1/2" pvc would stand straight up, in my case 30" lengths, and be bundled to fill the area of the barrel.
This would eliminate dead spots and channeling. the sand filter lateral would provide a gentle even upward flow. See the drawing: number 6 is the lateral assembly the 10 tubes that extend out from the hub have hundreds of holes in them for even distribution of water.
with simple mechanical filtration in front of this cleaning of the biofilter would be perhaps unnecessary or very easy to backflush.
