When I was building the equipment list, I wanted a very compact powerhead since I’m working with such a small tank. Originally I was going to go with a MP10, but as soon as I found the CoralBox RN-1 I knew I wanted to try it out.
So it’s very similar to an MP10 but there’s about a $115 price difference. It comes with a controller which you can use to change the modes, speed, frequency and feed modes. You can also set channels which allow you to run different modes and speeds throughout the day. The footprint of the RN-1 is very small, I think it has the same length of an MP10 just a larger diameter. As far as noise goes I haven’t had much time to play around with it yet, but from what I can tell it’s fairly quite on speed 2 and pulse mode (which is what I’ll most likely be running when everything’s set up).
I would really suggest this pump to anyone setting up a small tank, or really any tank that’s looking for a cheaper alternative to a MP10. Here’s a few pictures so you can visualize the size of it.
