If youre prioritizing the set up before the fish I would set up your full tank with everything the fish will need now before you buy your fish. That is professional advice. Look at it this way, a clean tank will give you more vibrant and active fish as well as less health problems which are very expensive to maintain in a large tank down the road.Actually I do priotize the tank over the fish... I wouldn't be here if I didn't. The tank comes in a month so I am gathering all the information needed BEFORE it has arrived. And money is no issue whatsoever I'm a 15yo kid with a weekend job who's parents strongly believe in independence but I know they will lend me a couple hundred dollars for absolutely necessary filtration. I'm just here looking for professional advice.
