Hello I am new to here. I hope to learn more about the hobby. As of right now I have an empty 180 gallon that Myself and a friend have sunk into my gameroom wall. Not sure where I want to go with it. As of now I have a 40 gallon long that I am going to make into a sump. First off I hope this is large enough for a 180. I plan on putting in bio balls as well as live sand and live rock. And algae that will consume nitrates. My goal as of right now is a fish only tank. And really want to keep a banded cat shark, and a horn shark. Sharks are my favorite, however I would really like some direction as to what I will need to home them. Any help to get the ball rolling would be great. I want to take my time 6 months to a year to get all needed equipment before even adding water into the tank. So let me know what kind of equipment I need to get this off right.
