The first equipment that you will come across is probably the aquarium lighting for the planted tank. Aquarium lights in addition to functioning as a light so that we can see the contents of the aquarium, as well as an energy source for plant growth. Without light, photosynthesis will not occur.
However, it does not mean that when placing the aquarium near a window and got the sun, then the aquarium lighting problem is over. On the contrary, excess light energy that can not be absorbed by the plant will cause the uncontrolled growth of algae in the aquarium.
Most hoods come with fluorescent lighting or incandescent lighting. Fluorescent bulbs are a better choice despite the fact that they are a bit more expensive since they have long-term benefits. They burn cooler, thereby not affecting the water temperature at all. Fluorescent bulbs have another benefit as they uses less electricity.
Fluorescent bulbs can be purchased in sizes that cover the entire aquarium. This will provide even lighting in all areas of the aquarium. There are a wide variety of fluorescent bulbs that emit different spectrums of light. Some of these will even assist plant growth. Some will lead to an increase in algae growth. Optimal plant growth requires a particular wattage, which can be decided by the size of the aquarium. Usually, 1 gallon of water will require 1.5 watts.
An average aquarium requires 8 to 10 hours of light a day. If you use incandescent lighting it is however better to turn on the lighting for a few fixed hours a day. Especially in the case of smaller aquariums, the water will become considerably hotter during the day. And at night, once the light is switched off, the temperature of the water will drop fast.
The best way to regulate the intensity of light for the aquarium is to avoid aquarium from sun exposure and replace it with aquarium lights. However, although the lights are essential for life in the aquarium, not all lighting types can be used. Improper use of aquarium lighting can actually lead to negative consequences.
