Your about where im at, maybe little more par than me.
SPS do best about 5-18" from top of water for me. But....I switched 1/4 of my 80 optics to 40s. Waiting for results
Is that at 100 percent? For me that's at 80 percent whites and 100 percent blues, 100 percent red and 100 percent greens.
I still don't think is enough so once I start the SPS again I may lower the fixtures another 4" or so.
