I just bought a CPR bak pak HOB
skimmer. I bought it used and am unsure how to set it up. I checked the site for CPR and they have skimmers like mine but there seems to be an extra acrylic box that I dont know what to do with. Also this may seem like a stupid question but the Rio pump that came with it is ok to put in the tank. I mean waterproof and all.
Oh and the filter media that goes in it. Is it absolutely necessary? I will get it if I have to. I am also running a pengiun filter without the biowheel in this tank.
Thanks for your help.
