Cleaned my Atlantis 2 screen this afternoon and was surprised to see that my normal Ulva growth had all but disappeared to be replaced with very dark green soft algae, some tuffer dark green algae (I have been getting more of over the last few harvests) and some slime. I tested my water for nitrate and phosphate a few days ago and my nitrate had gone up to around 10ppm and my phosphate to 0.06ppm. I am assuming the increase in nutrients has caused this so I have cut back on feeding my heavily stocked tank to just 2 feeds a day from 4. I have attached a few pic's of both sides of the screen and the algae removed.
My ATS has started to grow Ulva again, not sure why but it could be due to my NO3 increasing slightly which I do suspect.
