The whole idea behind preventing it is to make sure you are exporting phosphate by other means. In older tanks with sandbeds it very often becomes a problem sometimes called "old tank syndrome". Sometimes it apparently doesn't. In bare bottomed tanks it doesn't typically become a problem.
Water changes, running phosphate remover and getting your skimmer working are going to be the easiest ways to get a handle on it.
