• What should I set MY lights too?

    Your light settings are going to vary tank to tank. No one tank is the same. This table provides some very basic guidelines for where you should have your final program numbers at. Keep in mind for every tank you must first acclimate your corals to the lights.

    The chart works as follows. You take the depth of your tank from top to bottom, and your coral types, and look for it in this chart. The maximum percentages shown are general guidelines and apply to channels 3,4,5, and 6. Channel 4 is the white LEDs- so that channel’s output varies greatly from person to person. In general, you want to add about 10% power for every additional 6% of tank depth to increase PAR at the bottom of the tank.

    We recommend finding a color ratio YOU like- instead of chasing an arbitrary Kelvin rating. In general, it is simpler to adjust the ratio of channel 4: 3, 5, and 6 to achieve your desired color output. The below guidelines assume channels 3-6 are set equally. So if you choose to run channel 4 lower- you can increase the power of channels 3, 5, and 6 by 5% for every 10% reduction of channel 4.

    For example, a 24” deep mixed reef tank would normally set channels 3-6 to about 60% for the maximum peak output each day, after the acclimation period. Let’s say channel 4 is reduced by 10% to 50%- that means channels 3, 5, and 6 would be increased from 60% to 65%. That’s approximately what it takes to offset the PAR lost by turning channel 4 down.

    The Photon V2 Pro comes ready to use with our Reef Nexus App. However if you have an older V2 or the V2+, you can install our Reef Nexus Integration Kit to use our app: Reef Nexus Integration Kit

  • How do I tell if my corals are getting too much/not enough light?

    Always remember to keep an eye on your corals once you make any changes to your lights. Corals are living animals, and they will respond to too much or too little light, sometimes in immediate and easy to spot ways. Below is a table with some common coral reactions to too little or too much light- or just enough.

    Note: Bleaching and browning are progressive symptoms, meaning they happen over time. It takes at least several days for browning to occur, bleaching can happen in about 1-2 days. If you stick to the acclimation schedule your corals should not suffer any adverse effects. However if you increase the light output by too much or too little, the symptoms laid out in this chart can be helpful to determine what adjustments must be made.

  • I have an older light- can you help me figure out what model it is?

    There are several models that Reef Breeders has carried in the past 7 years, including some that have been discontinued and are no longer listed on our website. Knowing which light you have can help us serve you faster if your light needs repairs or troubleshooting. Below is a helpful chart that can determine exactly what model of light you have.

    What Model

  • So I see your color layout- but I am unsure what each color does? Can you explain this in detail?

    There is a ton of information out there about which spectrum does what for corals and the symbiotic zooxanthellae that live within their tissue. We have done extensive research on the topic and carefully developed our layout over years of testing. Below is a table that summarizes briefly the function of each color.

    Disclaimer: Each color serves many more functions than the ones listed below- and the layout is designed to be balanced in such a way that you do not need to stress one color over the other.
    Note: The ratio of Chlorophyll a to Chlorophyll c in corals is 10:1 a:c. Some proteins are only present in certain corals. Others, like peridinin and neo-peridinin are almost universal in coral tissue.
