Fish Only Tanks with Live Rocks (FOWLR)
These tanks can be run with efficient, with powerhead operated in the tanks for more water circulation. The normal set up is to use about " of CaribSea Aragonite Seafloor Special. This is topped by another 2" of coral sand. Alternatively ( preferably in my opinion ) use a large external power filter filled with biological media and floss.
In this case the tank can either have a bare base or an inch or so of coral sand. Regular maintenance is essential. This consists of regularly monitoring the water quality and changing 25% of the water monthly. Don't forget this when you are setting up as you will need facilities to make up this replacement water in a separate container before every change.
