Hello everyone! I’ve recent gotten 2 vipar spectra 300w lights! I mounted them 16 inches above the water and my tank is about 21 inches tall with about 1.5-2 inches of sand. I’ve for corals I have all softies ( acans, zoas, green star polyps, hammer and two anenomes) I was wondering what other people with about the same setup set their lights at before I spend the money on renting a par meter. Also any recommendations on par? Was thinking to try to get most of the tank to 75-150 par. Thank you all!
