one would neve "HAVE" to sump... I've seen 220+gal tanks just loaded with power filters, and it works great, just depends on what yo uwant to spend and have to look at...
I would probabbly have at least 1 canister, and 1 power filter at a min...
yea i just dont wanna have to buy 2 sumps, but i'll probaly get to sumps, a aqua clear and maybe a canister...i have a feeling im going with the 210 with overflow, 650 you cant beat it!
