I have started to use one of those black plastic pond baskets also. I
hadn't thought about putting them on top of each other like a clam
shell. I just put my pump in there along with some scouring pads and
plastic sponges and then covered them all with lava rocks. I was
figuring I might get some biological filtration in the pads, sponges,
and rocks. I also wanted to use all this to block big stuff from
getting to my pump. I will think about doing the clam thing next time
I work on the pond.
Thanks, James

Putting stuff in the basket isn't necessary, if you have a filter out of
the pond it is pumping to. In fact, it sort of defeats the purpose because
you will have to clean those eventually, and they cause more weight to
lifted out of the pond. Clam shelling the pump with no fillers and you
won't have to pull it up all season. ~ jan
