Unfortunately, a lot of people end up getting equipment and finding out they should have bought something different. A good thing to think about when buying equipment is planning for the future. If you think you will want to get a bigger tank at some point plan on getting a skimmer that may work for a bigger size tank but not too much for your tank now. I just ran into this issue myself by building an LED fixture and after a LOT of reading made my purchase just to find out a month later, I should have bought different drivers. Ended up costing me about 70 to correct my mistake. So basically if you think you want to get into coral, get lights that will support SPS because eventual you, just like everyone else, will want those in your tank. Happy Reefing!
