I follow the rule of common sense and leave it at that. too many people like to preach rules where there should be "commonly used setups" not all scenarios are created equal and if everybody folowed the same "rules" there'd be people with 5 acre ponds spending 1000's of dollars a month in electricity just to run a filter that turns over enough water to follow these so called "rules."
oh sure if you're settign up a new world cichlid 75g tank, there are many commonly used setups that work best, but that doesn't apply to the grand scheme of things.
