GSP purple changing white and coming off

[407Hunter]

Under mine below is pure white colored rock. Light and flow are more important to them

Gorgeous ! They’re getting good flow. I think light might be weak at 75par?

Thanks for sharing. I’ll try slowly moving them up

No macroalgae. Having a hard time finding any locally.
20 lb live sand. Sorry it’s a 20 G tank.
4-5 lbs live rock. 12 lb dry rock.
I’ll try separating the corals. Do GSP species do okay next to one another? The anthelias are close by because they’re shading the acros behind it from an intense T5 in my room (part of living room).

Gsp can go with other star polyps I'm fairly sure. Yeah I'd say go to your lfs and pick up a little bit more live rock.
You can make a ledge and partially shade your coral that way and it'll help a bit with the nitrogen
If that's not possible the best option is to still move the coral and do some daily water changes

Will try with rock. Hard to find that “perfect” rock. For now will move the GSPs away from that section. Will start with small daily changes and see how that fairs.

Thanks for the thorough response and follow up!!
