What to buy first fx5 or bigger tank

Same answer from the guys one above, get a filter first so it can be already colonized with bacteria on your old tank with fish then you have already a running and ready filter for the new tank.
 
so i got the fx5 today full of fluval biomax i have in running with my fluval 305 i ditched my hob i didnt have room for it
