Which are suitable for freshwater tanks that are somewhat shallow (these lights are not good in deep water penetration) as a supplement to water tanks or saltwater reef using actinic light (more of which later), and live plants. 6500K lights are lights on the green / yellow wavelengths.Natural light is also to be avoided for this reason. These are not good options for the lights in the aquarium, and to promote the excessive growth of algae. Lights rated at 5500K and below are typically incandescent bulbs in the red / yellow wavelength.Here is a brief description of the various lighting options. The color of light is expressed as the Kelvin scale, which measures the temperature of light. Without a prism, the different wavelengths of color are very hard to distinguish the eyes, but they are there. The rainbow that results is that the common view has been split into its different wavelengths of color. But consider what happens when light shines through a prism. coral tanks: These tanks of salt water that covers more than just fish, such as living coral, live rock, living sand, etc.In general, the lighting requirements for a salt water aquarium are the same as for a freshwater aquarium. Mollys are among the most popular brackish water fish. The brackish water in a tank is less salty than the one used for saltwater fish. Brackish water: Fish that live in freshwater and saltwater sources are said to perform live in brackish water.Other "animals" includes salt water tanks at sea stars, anemones, sea cucumbers, worms, and fan.
Popular saltwater fish are damsel fish, clown fish, Triggerfish, pufferfish, sharks, and more. That require the owner to prepare a salt water solution that replicates ocean water as closely as possible.
At home, you probably just buy a bulb that fits the schedules, put in place, and go their way.
Neptunes aquarium series#
Have you noticed that after a storm small balls appear on the beaches that look like straw? These are leaves of Neptune grass torn off by the strength of the waves.This article is part of a three-part series on the lights in the aquarium, be sure to read the entire series!Ĭhoose the proper aquarium lighting is very different from the lighting of your home. The fields of Neptune grass, according to annexe 1 of Directive 92/43/CEE of the Council of 21st May 1992, concerning the preservation of natural habitats and wild fauna and flora, constitute a natural habitat of community interest and special preservations areas must be designated for its preservation. It is an endemic plant in the Mediterranean. It forms a kind of thick meadow on the bed, less dense at greater depths. It is mainly found on sandy beds, though also on stones, from shallow waters to 40 m. Reproduction is preferably by means of seeds. It is a species of great ecological importance bioth the leaves and the rhizome house different types of beings: those with short lives that settle on the leaves and the older beings on the rhizome such as hydrozoos, briozous, poliquets, ascidia, sponges, epiphytic algae… It is considered a source of great organic material (food) and oxygen production (1 m² of leaves provides some 10 litres of oxygen a day).īeing a plant, its feeding is autotrophous and it therefore produces its own food from organic material and sunlight.Īs it is a fanerogama, it has flowers and fruit. Its stalks are rhizomes and are therefore underground, with fibrous leaf remains. Its leaves are tape-shaped with a width of approximately 1 cm and a length of between 30 and 120 cm. This plant is a marine fanerogama and therefore has flowers and fruit.
