I looked at building a Denitrator (don't know why I just looked at it) it looks like a pain in the butt, plus after talking to a few people I found out that often the bacteria will die off and leave you with a system that needs to be restarted. When people use a De nitrator, they feed it alcohol but in tiny quantities, I've still not figured out why for sure but I assume it's the sugar etc.
Brads right, sand bed, live rock, reasonable stocking levels should = no need for denitrator.
Marine aquarium? or Marine reef aquarium magazine has a great article this month about sand beds and how it's been proven that most nitrification occurs with in 2 inches of sand, no need for deep sand beds now?? Hows that for stiring up some ditrius.
