Powerhead or wave maker?

[whatcaneyedo]

Alternating and variable speed water flow creates a more natural environment in our tanks. There are a number of advantages to it over just having steady laminar flow from basic power heads alone. Coral tend to grow more uniform and natural looking. There are less 'dead spots': areas that receive little to no flow where detritus can build up. Also, waste should stay in suspension longer allowing the filtration system a better chance to remove it.
