Agreed the lack of biodiversity in dry rock seems to really impact the survivability of sps. It took me a year to finally be able to grow sps and i specially noticed i had no deaths when i started growing sponges all over my sump. Its been the same case for other people that have had dry rock too that once they start to see coralline and soonge growth sps seem to just take off.Here is the issue. Once my tank hit about 2 years, SPS just took off. It's really about biodiversity. Young tanks that are started with sterile dry rock, just cannot support SPS life regardless of what the parameter of the water are.
Do an @AquaBiomics test and you'll see the difference between a young tank that was started with dry rock, and one that can support SPS.
