Hi everyone, my name is Katie and I am completely new to marine aquariums (although my father has been in the hobby for years). I am just starting to gather things for a reef tank set up. I will be running a 46 gal bowfront with a 20 gal eshopps rs100 sump and overflow box, and reef octopus rw110 skimmer. This is all I've got so far. I am not setting up tank for a few months until after we move, but I am looking to purchase everything I need before the move. Here is where all my questions come into play that I could really use advice for. First, the sump I bought did not come with a return pump. I started researching return pumps today and found myself researching all day and still no closer to figuring out which return pump I should purchase. Many people say the higher the better (5-10x), then some say lower (3-5x).. I am absolutely clueless. Then I learned about the DC return pumps that you can adjust the speeds and that peaked my interest, but again, I am lost on what will be best for the tank. Return pump to tank will be about a 5' height. Second, lights... I plan on just having a few clowns, lps's and soft corals. Would I be okay to run a Odyessa T5 High Output with timer? Lastly (doubtful lol), what am I missing? Any other necessities? Tank, stand, sump, overflow box, sump, return pump, lights, skimmer..... I know I am forgetting something... powerhead maybe? Thank you in advance for any help that you guys can give me, I swear I pick up things fast and I'm SO ANXIOUS to jump into the hobby!
