down into the distribution. The riser (distrib-
utor) remains inside the tank seated in the
depression at the bottom. Plug tube with a

Fill support bed first. The media will not
always spill down inside the tank and may
need to be swept inside.The large funnel
(sold separately makes filling the tank easier
and neater. (Or an empty 1 gallon or 4 liter
container with the bottom cut out makes a
good funnel.)
