Looking Into many different approaches to new reef tank. Tank dimensions will be 84" 24" 24" around 200 gallon, sump will be 100 gallon and thinking of adding a DSB section in sump that will be easily taken off line if problems arise. Another idea would be to have an ATS with a skimmer, as for this would I size the skimmer to size of tank or still go a little larger than tank volume? Lots of people recommend twice the size of water volume but that seems a little extreme. I would think a skimmer rated at 300 gallon heavy filtration would be enough but im not sure where to go. I have been thinking the reef octopus regal series but am open to suggestions. Another thought was the biopellets. What would you recommend? Any combinations seem to work well together? This tank will eventually be SPS heavy.
