Hi, I have kept FW fish for 20 yrs and would like to start a reef tank. I have a 100 gal tank drilled in the bottom with a 35 gal wet/dry sump just lying around in my basement. Where do I start?. I need some opinions on what to use. A plenum, under gravel filter, thin or thick sand bed?. Wet/dry or just a sump with a skimmer?
