my nano has been up and running since last october. the water params are always kept good (0 ammonia, 0 nitrite, always below 20 nitrate). I've had green bubbles that open into green leafy algea. My husband removed some after it had opened but it's on about 1/2 my lr, not completley covering it but there none the less. i was just wondering about the best way to remove it, not necessarily chemicals. i have lots of life on my lr and don't want to injure anything trying to take this off. also if there's anyway to reduce it's growth please let me know.
