💡 What PAR Ranges Work Best for Different Types of Corals
Lighting is one of the most important parts of reefing. Too little light and corals fade away. Too much and they bleach. The key is understanding the right PAR (Photosynthetically Active Radiation) ranges for each type of coral.
At Gem State Corals, we grow and ship frags under optimized lighting conditions so you can replicate success in your home reef.
🌿 Soft Corals (Low Light Lovers)
Examples: Zoanthids, Mushrooms, Green Star Polyps, Toadstools
-
PAR Range: 50–150
-
Why: These corals thrive in shaded areas and lower light zones. Too much light can cause bleaching.
🟢 LPS Corals (Moderate Light)
Examples: Torch, Hammer, Frogspawn, Duncan, Acan
-
PAR Range: 100–200
-
Why: LPS prefer gentle lighting that balances photosynthesis with their feeding needs.
🔵 SPS Corals (High Light Demanding)
Examples: Acropora, Montipora, Birdsnest
-
PAR Range: 200–400+
-
Why: SPS have small polyps and need intense light for strong coloration and growth.
🐚 Clams (Tridacna Species)
-
PAR Range: 200–350 depending on species
-
Why: Clams house symbiotic algae that thrive under strong lighting. Place them on rocks or sand where light is consistent.
⚡ Tips for Lighting Success
-
Use a PAR meter or borrow one from your local reefing club.
-
Acclimate corals slowly to stronger light.
-
Stick to a stable photoperiod: 8–10 hours of light daily.
-
Remember: stability > intensity.
🎯 Final Thoughts
The right light makes all the difference in coral health and color. Whether you’re growing soft corals, building a Euphyllia garden, or chasing Acropora rainbow colonies, dialing in PAR ranges will help you succeed.
At Gem State Corals, we raise frags under proven light conditions so you know they’re ready to thrive.
