You saw my tub when picking up the shark? That one is a 100 gal tub. I went yesterday to a lfs in high reguard and discussed filtration for my 450. I will be keeping similar fish as you, messy dirty eaters. They suggested a sand bed, the 100 gal sump with a Precision Marine Bullett 2 skimmer with mag 18 pump and lots of live rock. I feel another mechanical filter is also needed. Good Luck, I wouldnt mind helping out with the setup, when the time comes...
keep in touch
