Hi tank m8s, I’m running my first reef tank and have a Waterbox Cube 20. I recently decided to install a protein skimmer in the middle chamber. However, this doesn’t give me enough room to put all of the activated carbon, bio balls, and filter sock into the first chamber. The third chamber houses my heater and return pump. I can fit both the carbon and the bio balls into the first chamber which leaves no room for the filter sock to go back in. Or if I take out one of those two things, I have room for one media bag AND the sock. For those of you with a similar set up, what are your opinions on eliminating the sock, carbon or bio balls? Many thanks!

Hi all, this has probably been asked a hundred times, but here comes number 101 😉 Simple question: what skimmer to use on a waterbox cube 20? Available options in europe (Belgium) aren't huge, popular ones are: OPTION 1: Comline DOC Skimmer 9001 (DC) (https://www.tunze.com/en/details/9001.000-comlineR-doc-skimmer-9001.html) (will have to modify this one for it to fit, because the magnet won't fit between the baffles of the back chambers, so we'll have to mount the magnet sideways) https://www.nano-reef.com/forums/topic/368761-tunze-9001-im-nuvo-fusion-20/ OPTION 2: Hydor slim skim 135 (https://www.hydor.com/en/slim-skim/) Tight fit, but might work. Have no idea how this compares to the Tunze model... Other than that I don't see a lot of options, maybe the Bubble magus QQ might fit, or the QQ2... But is this a really solid choice? I anyone knows whats best, please let me know! Thanks!!
