Well my personal preference is this. I've been doing this for a while now and have set up multiple tanks.
Skim Well
Have good, vigorous, random waterflow
Do not Overstock
Plan your livestock, and aquascaping
Grow Plants
Keep Salinity, and temperature as steady as possible
Use RO/DI water
DO NOT SKIMP ON BUYING GOOD FILTRATION AND EQUIPMENT
20% waterchange weekly
New carbon every other week
Filterpads weekly, or sometimes 2x a week
Low sand bed, or no sand at all
I encourage the growth of macroalgae if you can, if not, well, no big deal, but they will help you with waste removal.
Run ozone or UV. I prefer ozone. IME ozone is better for water quality, UV is better for parasite prevention. But both perform roughly the same task, and ozone is cheaper and more efficient. Ozone will make your water sparkle.
If you are going with a reef there are even more things you can do.
