Switching out the canister

Will this reduce the bio-filtration?

I had a 33 gal running and never used a canister filter, just used a Aqua Clear filter and 2 power heads actually Koralia Nano's. My tank had only softies and LPS's though.

I ran my original first two tanks, 72 gal and 95 gal with canister filters and when I took them off at first I was worried.

Best thing I ever did. Having said that... what do you have in your tank for corals, fish and how much live rock?
