A very important trace element for zoa's is iodine , that could be the problem as well.
if your iodine is to low , be carefull with dosing.. to much will be poisones
maybe try running just a phosphate remover if it’s really that high? Do you have a refugium at all? It looks like your running an AIO? I know some people run refugiums in one of the chambers. But I would work on getting your phosphates down they are way to high (saw you said they are at 40?
what do you feed the tank? that can contribute to high phosphates.
