If you love it, then there is still not enough SPS.
Eventually, they will get to where they start to die back from the size and start to kill everything underneath, but that does not appear to be happening yet. It breaks my heart every time that I have to pull out colonies, but there comes a point where you have to do it. When you cannot even get your hand between the colonies and the glass, then you have to do something. It gets easier over time.
I live in a somewhat big community of Denver and I have a hard time selling or giving away so much stuff. I found a local aquarium that will take healthy colonies (need to be mounted on sturdy rock) and I donate a lot to raffle for the local club.
The only suggestion that I might offer is to think ahead about what you don't really care about. You will need to know what to just cull and what to cut back. I eventually got to where I do not allow any MPB&S in my tanks nor LPS. I removed most of my stags and A. Carduus (dragons) last time, but I miss them now and have already gotten back CITR Red Dragon for the next reboot.
