In addition to water values and water flow, the lighting of a marine aquarium is the most important factor in the maintenance of zooxanthellae hard corals like SPS and LPS corals. This has developed a lot in the recent years, so a wide collection of lighting options are today available to the marine aquarist. Over the years HQI and T5-piping system have proved their worth; it is usually the first choice for the beginners. The acquisition costs of a T5 lighting are not so high, however the current power consumption of a marine aquarium is higher. Modern LED lighting of renowned manufacturers like ATI, EcoTech Marine, Maxspect or Giesemann are commercially very interesting and offer a lot of setting options. We would be glad to advice you!
