Charcoal ??/

How does everyone filter with charcoal? Right now I have a pvc pipe with holes in the bottom and a 1/4 tube feeding it from my return pump. HOw does everyone else do it?

Why use charcoal? It only removes important trace elements to will need to be replenished.. I think there is a fair amount of debate on this, but personally I do without... Anyway, if you insist, I would place it in the sump (in a filter bag), and just let the water flow over it...
