Lugmos12 Posted February 17, 2018 Share Posted February 17, 2018 Can corals survive strictly on moon lights? or what's the minimal amount of white light I can use? Quote Link to comment
romperstomper Posted February 18, 2018 Share Posted February 18, 2018 depends on the lights but my kessils are often just on blues with no whites and lps /softies do just fine . 1 Quote Link to comment

I have Current USA Marine Orbit lights on an Fluval EVO 13 with mostly softies and LPS and 2-3 pieces of SPS Quote Link to comment
Clown79 Posted February 18, 2018 Share Posted February 18, 2018 I run my 25g with only 15% white, my 10g it's 20%. It depends on the light, the type of leds, the ratio between blue to white etc. 1 Quote Link to comment

SaltyBuddha Posted February 24, 2018 Share Posted February 24, 2018 Type of LED makes a big difference. A 0.4 watt LED will give out substantially less PAR than a 3 watt LED at any given distance. The Orbits all run a lot of lower watt LEDs. I ran mine at 100% blue and 40/45% white. I now have a NanoBox with much stronger LEDs. Had to start at 45% blues and work up to 75%. Whites are only at 18% now. Check out the LED forum page. There is a really good post about types of LED colors and the purpose of their spectrum with respect to corals. Understanding how LEDs with with PAR will answer your question as well. 1 1 Quote Link to comment
