I think it all comes down to maturity and your nitrogen cycle. A tank that is finally matured with a very healthy bacteria population and multiple nutrient sinks tends to have very little pest algae growth.

Cheato does a very good job of this, mangroves and liverock as well but the person who stated flow is vital is also onto something very important.
