Question in regards to pearling. I forgot one night to turn off the fan to my lights and decided to take a peek at the fishes, so I turned on my LED moon lights and was quite surprised to see pearls against the faint LED lights. So, I thought that I'd turn on the lights, knowing that it's a big no no as it will startle fish, and take a look see around. It was quite a magical site, so magical I wish I was a fish to just brush up against the plants to start a bubble storm :tongue:. I didn't see any pearling before I turned off my lights so is it possible for it to pearl at night? I'm familiar with the Dark cycle where the stroma opens up to take in CO2 to make glucose, but does it necessarily produce 02 in the process?
