There are some larger units on the market designed to handle tanks of your size. MRC makes one, so does Deltec, and some other upscale reef equipment manufacturers.
Though if you're restricted by a budget, you could always try DIYing one out of 4-1/2" acrylic tube and 4" PVC fittings (that size tube fits perfectly inside of 4" PVC fittings) for about $50.
I have one of MRC fluidize chamber but i used it for carbon because i thought it would cost alot to fill with enough phosban for my system. If i buy another chamber for phos, How full should it be for my system. That is a pretty big chamber
