Filtration and lighting
Filtration is an important part of maintaining a healthy aquarium. It aids in removing harmful toxins and the cleanliness of the water, so make sure that you install a filter system that is the appropriate size for your tank.
Installing an air pump or powerhead may also be advantageous to improve water circulation and oxygenation levels. When installing aquarium lighting, select fixtures that meet the needs of your fish and any live plants in the tank.
