The lighting is WRGB 2 Pro 120 aquarium is 240 liters. CO2 3 bubbles per second is turned on 1 hour before the lamp and turned off 1 hour after it. The parameters are those in the photo. I fertilize according to the Seachem table from the photo. Unfortunately I got a black beard. My question is, is the light strong as it is set? What measures should I take regarding the settings and time?
