If your going to make the effort at building a sump, then build a sump that will handle your tank. No need for a sump AND a canister.
A backup to a sump, is another pump. Hookup two pumps that can pump about 400-600 GPH each, that way you have from 800-1200 GPH total when both run, but you still have 400-600 GPH when one fails. Evan at 400 GPH thats over 4 cycles an hour.
