I am planning on setting up a 20 gal nano, consisting of: soft,polyp,and mushroom corals, 2 or 3 fish, invert and cleaners. The setup I have in mind will use live rock/sand, 2X55 PC, CPR backpack, etc. Can anyone offer some recommendations/ advice before I get started? Thanks in advance. oh...does anyone have experience with coralife or finnex pc fixtures, was going to DIY the hood but dont trust my wiring ability especially if water is involved.
