Advanced Aquarium Fixture for Digital 24 Hour Lighting
quarium lighting plays a vital role in maintaining healthy aquarium inhabitants. Photosynthetic organisms such as plants or certain corals require a reliable light source to thrive. Many hobbyists focus on satisfying lighting requirements based primarily on fixture wattage. However, the length of time your aquarium lights are on (photoperiod) is just as important to the welfare of photosynthetic organisms as wattage.

How long do I keep the lights on in my aquarium? A. In general, the length of time your aquarium lights are on (photoperiod) should simulate the natural day and night cycle. A photoperiod of 10 to 12 hours a day will provide sufficient light energy for most photosynthetic plants and animals.
Fortunately, maintaining proper photoperiod in a consistent manner is easily achieved through the use of aquarium timers.

Advanced Lighting Option
External timers are an essential part of managing proper aquarium photoperiod. However, as an optional accessory, external timers are not often included in aquarium lighting systems. The new Marineland Marine Pro Light provides the ideal lighting solution for hobbyists.

The Marine Pro Light hood combines brilliant HQI metal halide lamp(s), high output T-5 actinic lamps, LED accent lights and an integrated digital timer for power you can control. This high output fixture has a high-tech digital timer built right in the unit to eliminate the need for multiple power cords and external timers. The timer controls HQI, T-5s, and LEDs independently for custom lighting options.

Improper photoperiod can affect the health of aquarium inhabitants. It can also encourage the development of undesirable conditions that affect overall aquarium health.

For example, an extended photoperiod can severely stress photosynthetic organisms. Photosynthesis involves periods of both light and dark to efficiently convert light energy into usable sugars for healthy growth. Prolonged imbalance between periods of light and dark can potentially stress and weaken photosynthetic organisms. Furthermore, excess light can stimulate the undesirable growth of opportunistic organisms such as nuisance algae.

Conversely, when the photoperiod is too short, many photosynthetic organisms demonstrate noticeable lack of vigor, color, and growth.
