I am setting up a Nuvo Fusion AIO 40L as a LPS tank (will probably end up mixed reef). I have a 3 shelf media basket for the back but i want some opinions on what to put in it. I will be running a fleece roller on one end, along with a 9watt UV sterilizer, and a Bubble Magus skimmer. Having a hard time trying to decide what to put in the basket other than maybe filter floss. I also thought about porous material but wanted some opinion.
