Corals for 75

[ZBT3091]

I have a 75g with an Orbit PC 4x65 (2 actinic, 2 10,000 k). My sandbed is around 4". I have about 75 lbs of LR. My filtration is a eheim classic canister filled with phosphate remover and carbon. I also have a nice euroreef sump with a dsb and lr. Right now i have a fowlr, with a few tangs, bflys, a foxface and clown. After i get rid of them, im looking to increase my LR and finally upgrade to a reef. Since my lighting is low, i think i am going to start with zoas and mushrooms, and maybe a few softies. I was wondering if there were any lps i could add. I was hoping i would be able to add some acans, or other brain corals. I was also hoping to add a clam. Please let me know any suggestions of corals. My questions was really if i could add the acans. Thanks
