Light Settings for Zoas?

bradb14 · Nov 20, 2020

Hi guys, anyone here use Zetlight 7300’s? I’m looking for settings (QR code shares) for them that favour zoas. I know they aren’t exactly the toughest corals to light up, but this is also more a consumption/heat issue as the lights are generating a lot of heat. I just want to experiment with a few but have no place to start, so post your QR code’s and let me try them out!

My tank is 1000L, got 2 lights about 80cm from the base of the tank.

Bumping this up for anyone with experience using Zetlight 7300’s

I don’t have any experience with this light but I have a lot of experience with led lights and If your trying to grow zoas I would start with all blue and Uv channels at 30% and whites at 10% and reds and greens at 5-10%. Watch the zoas and if they are stretching too much than start turning up the blue lights 10% a day until the almost lay flat. You can also increase the whites as high as 25% or more depending how strong of a led light that is but only after you’ve maxed out your blues and still feel like you need more par. Reds and greens promote algae growth but some red has shown to be helpful in coral growth.Of course this is all in my opinion. Good luck!
