The new light has been on for about week or two. glass is going green as seen in video. is that your standard algae? i know its a pain to get rid of. im guessing the only way to not have it is to start the tank off with water at plant level or only if more plants are present to compete for nutrients because my ottos dont seem to help effectively. My lights are on for 4 hours and then off for hour or so and back on for another 4. what else can i do to minimize it?
