Controling algae in your aquarium

Controling algae in your aquarium:
- Avoid direct sunlight on your aquarium.
- Don't leave the lights on your aquarium on more than 8 hours. Six to eight hours of light is recommended.
- Keep nitrates, phosphates and silicates at a low level. If you have a persistent problem - use reverse osmosis (RO) or deionised (DI) water, or specific adsorption resins (e.g. PhosGuard). However, note that although high levels of such nutrients may encourage algae, it is not generally possible to completely eliminate algae by attempting to reduce them, as algae can survive at levels below those which can be measured by a hobbyist test kit.
- Consider adding algae eating fish
