Having a 28 gallons or a 100 gallons is pretty much the same requirement...light, skimmer, heater, liverock. A sump is nice if you have room. I don't have one and been running my 75 gallons for 2 years without one because I have no room and everything grow like crazy and is very healthy. If you have experience for 5 years with a 28 gallons saltwater tank you should know pretty much whas is needed for a 70 gallons, as it is about the same.
