Almost every acan lord I get goes from super vibrant to an orange/brown color after about a month. I have them down low in the tank away from any direct flow. Parameters are as follows: PH 8.0 Nitrate 10 ish. Phosphates 0.03 Calcium 450 Alkalinity 9.0 Magnesium 1440 I use black box leds. World wide told me they do that under intense lighting, so they said to raise the lights and keep the acans in more shaded areas. Does that sound right? Or is there something I'm missing? I really love acans and want to have some nice ones for the lower reaches of my tank.
