Guide to Coral vs Par

[CG2000]

I made this chart based upon numbers Google AI pulled up, so let me know if any are off. Should be helpful for coral placement if you know the approx par spread of your lights.

If you have a Kessil 360x, you can get that info from a BRS video here:

Its nothing more than a general guide really. I have some of the coral listed under quite a bit more par than your graph recommendation. For example I have GSP under 500+ par and have to trim it back from the weirs every two weeks.

I guess R2R is AI2AI these days...

Yer, it’s just intended to get people in the ball park. I’m sure there’s plenty of cases where corals are doing great outside of these bands. I’d be interested to hear from anyone who has outliers in thier tanks and/or if any of my suggested ranges are egregiously wrong!
