4 bulb t5 + LED strip with 12 3W deep blue chips (not required but look good), 20 gallon sump with return pump, swc 120 skimmer and 2 little fishes reactor for GFO. Powerheads are tunze 6025 and vortech MP 10. Most of the nicer equipment I have was bought used or given to me. Simplicity depends on what you want to keep , how much livestock (mainly fish load) you want and how much work you want to do.
What are you thinking for livestock? Fish only or reef?
