Adjust aquarium lighting to support plants and fish how to relieve heartburn fast

It is also good to leave the aquarium lighting on longer in the winter, when natural light is less due to the season, for best growth and the healthiest aquarium plants. As the days lengthen, the aquarium lighting period can be shortened. Light Needs for Different Fish Species

When it comes to the fish themselves, aquarium lighting is mostly about you, not them. Lighting in an aquarium tank makes it easier for you to see and enjoy your fish, but it usually doesn’t affect the fish all that much. The nature of an aquarium, with its four glass sides and relatively small size, means that most fish are getting more light than they do in natural settings, whether or not you are using supplemental lights. Most fish don’t mind getting more light. A few species, such as cichlids and tetras, thrive on less light, and for these, too much supplemental aquarium lighting may affect them negatively.


Consider the conditions that a species experiences in the wild when determining how much extra lighting, if any, is required. Tropical fish have evolved under conditions that provided roughly 12 hours of light each day, so logic suggests that an aquarium with tropical fish will likely need a combination of ambient and aquarium lighting for roughly half the day. On the other hand, cold-water species such as goldfish, minnows, ricefish, and danios (zebrafish) are from temperate climate zones where the daylight hours vary according to the season. Here, you might want to vary the amount of light over the course of the year. To create a more natural environment, match the length of aquarium lighting to what the species experiences in its native environment. Light and Algae Levels

If excess algae is a problem in the tank, a contributing factor is usually too much light. Algae are tiny plants, and too much light causes too much algae growth. Reducing the time the aquarium lights are on to eight hours, or a bit less if necessary, will help reduce the algae growth.

Monitoring algae levels can, therefore, help you determine if your lighting levels are appropriate. If you begin to see excessive algae, shorten the periods of light to retard the algae growth. But remember that it’s also possible to have too little algae in an aquarium. Algae are a food source for some fish species, so you don’t want to eliminate algae altogether—just control it.

Remember that aquarium lights don’t only produce light—many of them produce heat, and sometimes a lot of it. LIghting types that produce heat include incandescent, VHO-fluorescent, and metal halide. In smaller aquariums, these types can cause a significant rise in water temperature, sometimes enough to kill your fish and plants. If you use one of these types of lights, make sure to monitor the water temperature constantly, and avoid leaving the lights on overnight.

Standard fluorescent lights produce cooler light and are a better choice for most aquariums. You can leave them on for long periods without danger, and many tropical fish and plants thrive under fluorescent lighting. Tips for Using Aquatic Plants

​ True aquatic plants must be kept wet at all times. If they are even allowed to partially dry when transplanting new clumps, these plants may suffer for weeks, or even die altogether. And live plants should never be removed and cleaned under running water. For true aquatic plants, such treatment will damage or even kill the plants. Some aquarium owners do this because they want to remove whitish slime on plants, but this slime layer is actually good bacteria. Fish eat this slime from time to time, and it is entirely natural—part of what keeps an aquarium in homeostasis.

To get the best looks out of your plants, plant them in the substrate and ensure they are well anchored to the bottom of the aquarium. Planting in thickets (bunches or clumps) is an eye-catching style, but don’t use too many plants in a single thicket. The plants need room to grow and get full light on all the branches and leaves, which won’t be possible if the thicket is too dense. Ideally, your fish should be able to swim cleanly around and through your aquarium plants.

Many aquarium plants will increase their numbers naturally. Vallisneria and similar plants send out runners under the substrate, which in turn then sprout upward next to the parent plant. These new plants can be left to grow where they sprouted, or you can cut away the runners and replant them elsewhere in the aquarium to start a new thicket.
