Arrange the rocks into a loose open pattern. Direct one water jet, like the filter exhaust, along one side of the tank. Aim it slightly inward so that the water spins in a slow vortex. Add a power head as necessary.  Water should be moving through the entire aquarium so the live rock and sand can filter it biologically. This keeps biological material from building up, and it keeps food suspended so the fish will have plenty of time to consume it. Saltwater fish, unlike freshwater fish, are generally used to keeping position in waves and are not upset by vigorous water movement. This removes undesirable material, including suspended algae, from the water so it does not dirty the water as it rots. While replacing a mechanical-filter cartridge more often might also be a good idea, a big protein skimmer is perhaps even more effective in removing organic sludge.  Adding the skimmer air line will change the water level in the skimmer. Be prepared to adjust the skimmer so the water doesn't rise too high and spill out of the aquarium. The size of the skimmer will vary depending on the size of your tank. For example, a 60 gallon (227.1 L) skimmer will work on a 29 gallon (109.8 L) nano-reef. A magnet cleaner has two parts, one piece on the inside of the tank and one on the outside of the glass. As you move the outside piece, the inside piece moves and cleans the glass. This tool will allow you to do quick daily glass cleaning without putting your arm in your tank. This works best if the lights are not extremely bright so the glass will have little coralline algae on it. This will greatly reduces the risk of heater breakage. Heater capacity should be on the low side because the lights and pumps create some heat. Low temperatures from a cold house or insufficient heater capacity are less likely to kill the fish than excessive temperatures from a powerful heater.
