Hi, guys! Finally I have a clue about what's is causing the algae that I'm fighting for many years in my tank. It could be a problem related to photoperiod.
My tank photoperiod lasts for 10 hours (2 h of low light at beginning, 6 hours of high light at the middle and 2 h of low light again at photoperiod end). My lights turn on 3 pm and turn off 1 am. My tank receives indirect sunlight during the day because it's next a window. The problem is some of my plants, specially rotala wallichii, opens its leaves about 4 hours before the tank lights turn on and closes its leaves about 4 hours before the tank lights turn off. I suppose the moment the plant closes their leaves it's stopping photosynthesising, right? If so, the plant isn't using the light and it's inducing indesirable algae. That makes sense? If this is really the problem, how could I fix this? Moving the photoperiod 4 hours earlier and keeping the duration of ten hours? Thank you.
