Sorry for ur loss bro, its common in this hobby. Not likely will refund cos the LFS can just say its ur water issue. Its hard to pinpoint and not fair to LFS also. Sometimes it can be our fault, rough handling, water issue etc...thats y online purchase is cheaper but comes with risk, the color can be off or the coral is sick or receding, sometimes the LFS cant tell also as they have many lifestock to look after..so sometimes go shop buy better, take time to see see look look, inspect pest, apitasia, receding tissue etc, den buy with confidence, sure u are paying premium, but at least it pass ur own QC and wysiwyg. Dont be dishearten and keep going, u will soon find ur favorite LFS which provide healthy corals. Sometimes it can be the water, flow light also, maybe LFS tank parameters quite different from urs and coral will shock, the acclimation probably wont help as corals are slow adapting animals, this is just my theory though.
