Good evening Smorg family.
I was messing with the tank and broke out my PAR meter just for something to do. I know most online retailers and a lot of hobbyist say to keep goniopora in low - moderate light. I have seen anywhere from 50 - 250 mentioned. Actually only one time at 250 and that was in 'extreme' cases. Well, I've had my goniopora probably 6 weeks now. It came from a friend's tank who aquacultures LPS and SPS. He keeps most his LPS in 300-350 PAR during a 5 hour peak period.
Anyway, I got my goni in and put it on the outer edge of my tank. About two weeks in I noticed it wasn't happy. So I moved it to a spot directly under a supplemental light I have for the magnifa anemone. This is on top of the Kessil a360x running at 90% intensity during peak, mostly white, very little blue. Same as my friends tank. Anyway. That spot averages 325-350 PAR for 5 hours a day. Since moving the goni it has grown considerably.
Sorry for the blurry pic, my photography skills are lacking. I am going to write an article which will more than likely ruffle some feathers regarding PAR and spectrum.
