75 gallon display tank, newly setup 30g sump with over rated skimmer. Fuge chamber is fairly small at 7"wide,12"deep,14"high. I am unsure if I should have a deep sand bed with these dimensions... My main point of sump is for pod population since my skimmer seems to be doing okay with nitrates for now. Suggestions on what you would do with the refuge? I am planning on having a fairly heavy bio-load.
Thanks
