Issues With keeping SPS

I agree with @fushi here. The XR15 Blue is designed to provide a proven spectrum with all channels set to 100% and then using the overall intensity to adjust. As mentioned take the adjustment slow. And since you are adjusting channels instead of overall intensity, I think you will need to do this manually rather than using acclimate feature.

And I’ll make another gentle nudge to a gentle bacteria product to help with the nuisance algae rather than chemicals.

Are you putting the new corals near the sand bed and slowly raising up?

I know its been mentioned a few times but I believe your lights are the problem.
White light is needed.
I would recommend turning all color channels on 100% on the xr15 blues then slowly work your schedule intensity up.
If you are getting more nuisance algae than you and your cleanup crew can handle bringing your nutrients (mainly phosphates) down will help.
However I do not recommend dumping a bunch gfo in as big changes are not good.
You may want to try some macro algae for a more gradual lowering of nutrients, this will allow you to find the sweet spot where nuisance algae grows slow but you can still detect nutrients in the water.
