no you don;t vacum into the sand as the sand is so thick that it doesn't allow food to get down to the bottom like the gravel does. So just hold the vacum a little ways above the sand and the debris will get sucked up into the vacum.

I recommend sand.

thanx sounds like it will cut vacuming time in half if no more

yeah it is really simple.

The main cartridges are different from the refillabel media cartridge. Without almost destroying the main cartridges you can't get the carbon out. Some people do it but I think it is a waste when there are other filters that are much better. Ideal HOB is an AquaClear with a DIY BioWheel built in.

does the refillable media cart come w/ the E 400

Not that I have seen. I have seen a pic posted, basically just a stainless steel rod/wire holding in place at the output. Just work with what you have or can find.

what about magnum 350 it has bio wheels w/ a canister

I am not a fan of the Magnums at all. The internal arrangement is very inefficient and not very customizable. There is a reason it is the only one I know without trays. It would not be a bad idea if you know you already have enough or almost enough filtration, but I would not give them much of the filtration responsibility.
