Slow Growing SPS

I'm not sure if that frag is bleached.

Hello,
I agree. Most likely the coral is just light colored rather than having expelled all its zooxanthellae from stress.

Cheers,
Kevin

Thanks everyone. I just thought of something. All my SPS are growing good with decent color, I have no coraline algae on the glass. The cube has been set up for close to 3 years and I have not scraped the glass once (not complaining). The coraline algae is on the power heads and overflow for the skimmer but never on the glass. Do you think the water para. is little off?

do you have a lot of coraline on your rocks?

btw i know boomer gave you all the evidence you need about iodine but i would have to agree with them iodine imo unnecessary
