When I first set up the aquarium, I just put a new filter with a product to increase cycling speed. I had another filter running in an older aquarium but I thought that at least the bacterias of the later part of cycle (the ones the convert nitrites into nitrates) would starve in the first days.
So I thought I would wait until I could detect amonia and nitrites in the tank (which happened today). So I ran and brought the old filter. Am I thinking wrong here? I hope not. If the level keep climbiing, I'll do a PWC
Today, during the morning, they were without film and without people around them. So when I arrived they got scared with every move I made. They also got scared when I turned on the plasma. Some of them even kept looking at it for a few seconds. After a few minutes, they seemed to ignore it.
I think I can only test the effect of the plasma in a couple of weeks when the exhibition ends.
Tomorrow I'll test the tank again.
This are still images from the film. I only had time to model two of the species in the tank.
