How to Regulate Aquarium Lights

The fish and plants in your aquarium need light, but you need to control the brightness. Of course, the size of your tank determines the number of hours you can keep the lights on but in most cases, the time ranges from six to twelve hours. What follows is an overview of how to make sure the level of light in your aquarium is ideal for both the fish and plants.

When to Cut the Hours

When there is too much light in your aquarium, it is very probable that you will have to deal with an algae problem soon or later. To prevent this from happening, be sure to trim down the light time to at least eight hours. Algae don’t thrive in dim light.

Other than that, the species of fish in your tank may determine the brightness. Cichlids, for instance, flourish in faint light and so are the tetras. You may also consider the amount of light in your living space. If there’s enough, you may not require aquarium lighting.

When to Increase the Hours

Live plants may be the only reason you need to increase lighting hours. In such cases, you may consider sticking to twelve hours a day. Again, the size of the tank and the plant species may determine the number of hours (it could be more than twelve if your aquarium is large).

Try to Maintain a Consistent Pattern

The primary challenge of increasing and decreasing your aquarium lighting time is to keep the pattern regular. Sometimes you may not be in the house, or you could even forget to check the level of brightness. The best thing to do, therefore, is to automate the process.

Look for an affordable timer and connect it to the lighting unit. Be sure to set it as per your needs. That way, you can rest assured that your fish and aquarium plants will get enough light even when you’re not in the house.

The other must-have tool for an aquarium owner is a sump. By design, a sump undertakes to ensure that the volume of water in your tank is at its optimum. The ripple effect is that the aquarium’s salinity levels remain healthy for both the fish and plant. A sump also dilutes fecal matter and other waste material.
