Looking at this for my 46 bow. 20 inches from light to substrate. Any info on par for that height? Maybe a price (ish) to know if I can even afford it. I'm on a tight budget after buying planted + for my low light 55

Par in clear water on 20" tank will be about 70 micromoles. It's a rough estimate but on a cloudy 24" tank it was 60 micromoles.
