I've had some melt before from low alk. Try bumping yours up to 3-3.5 meq/l and see if that helps. I've also had some just randomly melt...

are they recieving too much light?

is salinity stable? make sure the tank not getting large volumes of water topups for evaporation?

maybe bump up the magnesium to 1250-1350. i read in calfos prop book coralimorphs like good magnesium levels

is your temperature stable and below 28 degrees celcius
