That's good to know, I wasn't aware of that. I run my blue's near max during middle of the day, but I always keep my whites at around 5-10% depending on where my blues are.
Probably nothing. I have 90 lb's However added bacteria, and used ammonia to start the cycle. My rocks changed a little darker but not much. Are you adding anything? Are you testing? Ammonia, Nitrites, Nitrates?
I am testing weekly, my latest test is above - however I didn't check for ammonia.
Positive that's GSP. There's little white spots where the polyps are wanting to grow. You'll see it spread like a weed once your tank finds its happy place. For the GSP to look like that though would suggest that something in the tank isn't where it should be. You could try the lighting like the other dude suggested. Just don't make multiple changes to your system simultaneously or you'll end up with more problems.
I mean that completely explains why I thought it was fake coralline lol. That's awesome, I actually love GSP and would love it to grow out.
The only other thing I could suggest is to test MAG. With my tank I used to go forever without testing MAG because I read that nobody worries about it. I ended up with an unknown deficiency and I could never get coralline to grow until I finally tested MAG and fixed it. I'm not assuming that your tank is just like mine, but if the information is helpful then awesome.
