Attached is a Photo of my all my research to set up a 180gal reef tank at a cost/quality price. Taking into consideration i don't have back up equipment on the list, is there anything that could be swapped out for cheaper alternatives (if its not gonna crap out on me in less than 2 years)? Anything I'm Missing? Planning on running hardy corals eventually, no SPS to start out (would these lights work for SPS if I got a 4th?). Still undecided on a skimmer, Recommendations? Im all for getting that price down.
