what are you looking to order? if you are ordering corals i can help you pick some that you may actually be succesfull keeping, i would stick with softies until you get a good handle on how all of the parameters work, and have test kits for calcium, alk, ph, magnesium, phosphate, nitrate. I recently tried my first hard coral, and it died overnight... sadface....lol, apparently my numbers weren't good enough!
