advice for my new set-up

[reefwars]

thanks for the advice, for my skimmer im going to be using my vertex in-180 my tank is going to be around 150-200g and im going to be using my mag 12 if possible im going to be looking into the vortechs as well my problem is the tank is 4'x4' square so i need flow to travel everywhere ill have three return lines ran through the over flow and im thinking thats where the vortechs or other power heads will come in, im not keen on power heads especially in this tank lol

i am seriously wanting the controller im lookin at some ideas and its going to be a huge part of my budget

agreed on the chiller untill next summer anyways im just in the curious stages

not sure yet on the dosing either as im still info'ing around im liking what i hear about zeovit and im still undecided if im going to run pellets.my problem is if i dont incorporate or allow for space now i wont have it later ,this tank is going to sit right in my dining room right in the middle of the floor to walk around

how about co2 what are people using it for and is it something i should be looking into or need??
