How many fish have you killed? How many more are you going to kill before you learn?
Your filtration is not good. Certainly not for a heavily stocked tank. A bio wheel & rock is good filtration for a moderate stock, not more. And even then, only of you do regular large water changes.
I have a serious issue with the ignorant & irresponsible manner you are approaching this hobby. Fish collection negatively impacts reef inhabitant populations around the world BUT if undertaken responsibly by collectors, distributors & aquarists, can be maintained in an ecologically sustainable way. You do not fit into responsible aquarium keeping.
You mentioned you no longer buy from your LFS
because they are 'rude' and I can't help but wonder if you feel that way because they are giving you the same advice you're getting here - the advice you continue to ignore over 600+ posts.
You need to STOP and learn the basics. The most basic principles of reef keeping.
