Hi, was thinking about setting up a 20 gallon long or high tank (no corals) and I need help on what I specifically need to set it up. Also, on a budget to hopefully keep the items under 200$. Some sources I have found say you need a HOB filter while some say all you need is live rock and a Power head. So what do I need specifically for filter wise and other necessities for setting it up and what gph is the best. Also, what would be some good beginner stocking options too?
Thanks!
Thanks!
