I have a 12 gallon tank and already have 2 mushroom corals, and 1 rock of star polyps. I would like to start getting more, but I don't have any powerheads. First of all, I don't know anything about powerheads, other than they move the water around! So, I have a few questions. How many should I put in? And if I get the powerheads, are they self-powered, or do I need something else to power them?
Thanks for your help!
