Its tricky because people dont understand bioloads and water volume. From what ive learned, just take the cycling process very slow, use lots of liverock and sand, slowly add the bioload as each addition will give a small hiccup in the BB and water params. So dont over feed, slowly add life, keep a close eye on water evap (smaller tanks salinity swings harsher because of water volume. One gallon of evap in a 210 gallon tank is neligible and 1/2 gallon evap in a 5.5 can be a tank crash.) and its harder to pile equipment onto the tank, light options are harder to come by.
