LED Fkoid light in 45 gal tall
36L x 12.5W x 25H Marineland 45 Gal tank. Substrate height 3 inches. Which is the best light to grow medium to high light plants? Considering light sits 1-2 inches on the top of tank and a glass conopy in-between, light has to travel approx 23 inches. Which is the best light to grow carpeting plants? Planning to put two LEPOWER 50W LED Flood Light Outdoor, 4000 lumens each hanging 6 inches from canopy, total 100w and 8000 lumens, this will yeild 46 lumens per liter. I have pressurised CO2 injection. Will two of these in said configuration too much light and will it have algue problem? Please suggest.
