After your tank is finished cycling, you will notice a large spike in your nitrate level. As nitrate is potentially harmful to tank inhabitants, it is important to get them down. First, perform a 50% water change to help reduce the nitrates. At this time, it is safe to plant macro algae. Macro algae absorbs nitrates and phosphates the other nutrient that will cause nuisance micro algae to form. When the nitrates are stable at under 15ppm, then you can add your clean up crewhttp://www.agritura.com. Your cleanup crew should be geared for a younger tank. As diatoms are likely to be your tank's first problem, make sure to get a clean up crew stocked with ceriths and nerites.

Anywho, wait for the tank to cycle. Then ghost feed and add the CUC. Make sure to add some food from time to time to keep them alive, until fish are added.
