Hello i am setting up a tank this weekend. Its a 55g with a 20g sump. I will have a single 250w MH in the middle of the tank and 2 VHO's. For return i will have a Mag 9.5. I also have a berlin protein skimmer. I was wondering if i set it up now would i be able to put in a few sps by the middle of march? I am asking because there is a huge frag swap then and i wanted to pick up a few sps not many tho. I was wondering if i can do this or not. I know i dont have much flow in the tank now but i will be adding a few more pumps by then.thanks
