Hello everyone i am knew to salt water tanks and i am getting a 72 gallon bow front tank. I am going to just be doing live rock and a couple fish to start off. I would like to know all about the sump pump because the tank i am getting is going to be using one. How much is it going to cost to get a sump for a tank this big? What do i need to know about it and what items do i need to make the sump complete. Does the sump work as a filter or am i going to need a separate filter for this? Also am i missing anything else for this tank? i would love it if someone could help me out with all of this. I am just a younger kid not looking to spend large amounts on my tank yet (i know it is somewhat pricey but i would like to spend as little as possible to start) thank you for your time. i would prefer pm unless you have some other form of contact.
