Hi there. Starting out on my first planted tank. Have a juwel rio 400 holding 95usg with t8 lighting 2x36w giving me 0.75wpg. Will fitting reflectors give me a better wpg or just increase the amount of light being directed into the tank? Sorry may be a silly question but new to the planted side. Hopefully got the rest right. Tropica planted substrate topped with sand. jlb system 2 co2.
