I have a 36" Chihiros WRGB 1 that is about three years old at this point. It was an absolute powerhouse on a 22 gallon long, but now on my 75 gallon the light seems to be pretty low intensity. The rotala in the middle, for example, is supposed to be Rotala H'ra, and it barely gets orange. Buying a new light is currently out of my budget. Do you think I could get better color out of my plants by doing a longer photoperiod? I'm currently at 8 hours and looking at 11-12 hours.
One reason I ask is that I just saw that Cheattha Sae-Teaw (I almost certainly butchered that) is using a 48" Chihiros WRGB 1 on a 60" tank and getting pretty spectacular reds. His photoperiod is 11 hours. I believe Christel Kasselmann also runs 11-12 hour photoperiods.
Would I just be spinning my wheels? Is it worth a try? I'd love to hear any input.
Edit: Just looked up his name, and I did butcher it
