The only light that gets threw to the tank is a small piece of glass that runs the lenght of the tank plus its dirty and scratched to hell, the front and back are the solid black pieces. i want a green algea tank (walls) and i thought removing the lid would help, i have a brown algea problem now but think this might be a problem. would removing the lid completly if the tanks filled be ok? i have the lid off now and the tank is glowing, some water mist from the air stone is hitting it but can wipe it down everyweek. any thought or ideas thanks
