Steve, after many years, i am about to finish my experiments (Low Nutrition) the easy , low cost, so NO GFO, NO active Carbon, NO Berlin Sucks etc. No BioPeletts, just 12 ml. of Vodka for 280 Gal. system (easy to manage) and Protein Skimmer, i also use Diatom Filter to clean my sump every time i see any Detritus precipitation (actually , just use the sump as a Tank, for more water only and room for Protein Skimmer) I think #1 problem is , how NOT to build the Detritus and how FAST to remove, there is a GOOD reason why jackson6745 decide to go with that kind of Aquascape, mean more flow around, less Detritus precipitation, if you have a sand , i will consider "Luxury" need constant clean up. Water flow is the KEY ,NOT to much, NOT less, just good enough to push the Detritus to Protein Skimmer.About Bacteria , that anther issue, the more you dose , the more problem show up, low PH, etc , NOT all the corals like so muck, Thanks to HUB Bacteria Tests, who help me to find up , were i am. I repeat , the KEY is , How FAST you remove the Detritus. List that my opinion.
