Sorry for the header as I could change it after posting , but you all get the point. Parameters are alkalinity 7.8 and n03 is 4.5 PO4 is 0.11 calcium is 420 magnesium is 1300. I had kessils running at about 60% power I just turned it down this week to 40% as I think the light is burning corals. I don’t have a par meter so screwed on that.. I also use T5 lighting and orphek blue led bars.
