Hello men, nice tank, how many Lumen/Litter do you have there, whats the quantity of light you have?, I have about 6 tanks now, I only use LED lamps DIY, I love it, low power consumption, Bright and long life, no cons until now, no problem at all with the red plants, if you have enough nutrients (Ca and Fe), Co2, a good light and if you dose, well, your plants will be ok! I use RGB LED, red, and sometimes blue, to cover all the spectrum, as you know this RGB looks white but the plants take advantage of this, you should also know that white light has all the colors of the rainbow on it, please see this fixture below, I have 12x3W 6500k on each side and 10x3w RBG in the center (34 LEDs total, about 6800lm/L, 90lm/l). this is an actual project, I ha va no more pictures :-(
see this picture, can you say if this is green, blue? maybe a little red? its RGB
Regards!
