SPS graveyard, aka my tank.

If you decide to remove the sand, I would change a few cups a day till it is gone so you don't run the risk of cycling the tank. I would also suggest getting a different type of 2 part. Like Bulk reef supply or ESV.

Perhaps the corals you get are raised in high alk and get shocked going into your low alk system?
