I have a 30cm(approx 12") cube planted aquarium lighted with a 12W Chihiros A201 led. Plants are all growing well. Even the cuba which was planted 1 week ago is started to spread fast, but some of the reddish plants like the rotala rotundifolia and colorata aren't red. CO2 on drop checker is always lime green and I also tried varying the EI dosing by leaning the nitrates and by increasing the micros, and plants still grew very well but no color change. I was thinking of changing the light, maybe with one which has some rgb light. I found the Finnex Fugeray Planted+ which has some white blue and red leds and even some good reviews online. Do you think it will be better for the rotala plants? Or do you have any other light suggestions of what I can do. Thanks.
