LEDDY SLIM MARINE DAY&NIGHT

The flat, futuristic shape of the lamp and the fashionable, white or black color make it a perfect match for modern aquarium tanks and looks great in any interior. In addition, it is universal – extendable brackets allow it to be installed also on tanks of non-standard sizes. It can also be suspended above the aquarium to the ceiling or a special rack using the LEDDY SLIM HANGER accessory set.

The LEDDY SLIM MARINE DAY&NIGHT LED lamp is equipped with the Day & Night function. It works in three operating modes: DAY / DAYBREAK / NIGHT. DAY is the basic and strongest light, to illuminate the aquarium during the day. DAYBREAK is a reduced power of daylighting to 50% plus blue light. It works well as the first mode after the night and when feeding fish – especially in the case of timid cast. NIGHT is a blue glow that allows unique observation of the aquarium after dark, including nocturnal fish and animals. Day & Night lighting will beautifully display the arrangement in the aquarium both during the day and at night, and will also make the interior of the room in which the tank is located more cozy. The DAY / DAYBREAK / NIGHT operating mode can be changed after switching the module off and on with the switch in no more than 5 seconds. Switching directly to the DAY mode takes place after switching off the module for a period longer than 5 seconds and switching it on again. It is best to automate this process by using the modern SOCKET DUO aquarium controller.

Open aquariums and their lighting

An open aquarium is a great option for people looking for modern and designer solutions in the aquarium hobby. It is preferred especially by enthusiasts of styles such as Dutch, Japanese or biotope aquariums. Thanks to its natural appearance, an open aquarium can become an attractive element of interior design and attract the attention of guests. It also provides better humidity in the room, which is especially beneficial for people suffering from respiratory diseases.

Open aquariums are tanks without a lighting cover. In their case, lighting mounted on beams or hanging lamps is used. Lamps for mounting on the side edges or on the rear wall of the tank are also often used. The latter are dedicated to tanks with a smaller capacity, the “nano” type.

White and actinic light

A marine reef aquarium should be illuminated with two types of light that differ in color, or – technically speaking – color temperature. Color temperature is a concept coined by theoretical physicists. This is the temperature to which a hypothetical “black body” should be heated to make it emit light of a specific color. It is expressed in Kelvin. The main type of light used in reef aquaristics is white light. It provides the energy necessary for photosynthesis for zooxanthellae, and also perfectly reproduces the beautiful colors of marine animals.

The second type of light necessary in a reef aquarium is the so-called actinic light, intense blue to slightly violet with a color temperature of 16000-24000 K. It helps in imitating the effect of sunrise and sunset and contributes to better coloration of fish, as well as corals and other sedentary invertebrates. In the case of many of them, it also enhances the effect of the so-called fluorescence (animals seem to glow in the twilight, which gives them an extremely attractive appearance). It also has a very important, although not fully scientifically explained, significance for the proper functioning of many marine organisms. For example, the use of high-quality actinic light often stimulates some species of saltwater animals in an aquarium to breed.

How much light in the aquarium?

How much light does a reef aquarium require? It is usually used to convert its power to the liter of the aquarium. In the case of using LED modules, the optimal amount is from 0.6 to 0.72 W for each liter of water, assuming that the tank is not higher than 55-60 cm (in the case of higher tanks, this amount increases rapidly). About half should be white light and the rest should be actinic light. Along with the acquired experience and preferences of the aquarium owner, the proportions of white and blue light can be modified by adjusting them to the desired growth rate of corals and the stage of tank development.

How to combine white light with actinic? Well, the former should be lit continuously for 8-10 hours a day, and the latter for 10-14 hours. It looks like actinic light should turn on first, then white light should come on after about an hour or two. After the mentioned 8-10 hours, we turn off the white light, and the actinic light should go out about an hour or two after that. It is best to automate this process by using the modern SOCKET DUO aquarium controller.

The “day” in the aquarium can be practically any part of the day. If the tank is located far from the windows and is illuminated only with artificial light, the times of switching on and off the lighting can be virtually any. It’s best to simply adjust them to our preferences and hours when we are usually present in the apartment (e.g. “dawn” at 3:00 pm and “dusk” at 1:00). Then we can freely enjoy the beauty of our own “piece of the ocean” brightly lit.
