hehe ok... i guess combo it is... as soon as i find relatively affordable prices on the canister.

::edit:: all my buddies think i'm crazy btw... cuz i'm planning out ALL the costs and stuff for my tank equipment. like i have it all out on lists:
cheapest NEW coralife lunar aqualight 48" = $212 + shipping
eheim 2227/2229 = looking on ebay, craig's list, and aquabid
emperor 400s x2 = 35.99-37.99 each on bigalsonline.com
72 gal bowfront stand = boyfriend is buying for me, but the cheapest price i've found is i think $250ish..
titanium heater = $16.99 (i think have to double check)
looking into UV sterilizers, live plants, etc.
haha so i've racked up quite a bill w/o even buying anything yet! but i like to plan things ahead so i know how much i expect to spend... *sigh* and then i found that 125 gal on craig's list for only $200 and i just about cried... everyone i know (who happen to NOT own any fish of their own)... tell me to just concentrate on setting up my 72 gal... so i guess i'll start there. once i get that set up, i'll hunt for another good deal.
