Do you have a uv sterilizer? Or access to one? How large is your tank?? 8-12 weeks would be better and some more aggressive water changes 25-30% unless you have very sensitive corals or clams in system, then just 10-15% is fine. After the qt time has passed, do not try to restock too quickly. That can set up even more issues. Good luck I know its a hard thing to go through. Been there done that
