I think we'd all do well to just leave this one alone for a while, like several have suggested the OP do with their tank. The difference between debate and recommendation are less and less clear, and likely to cause confusion. He's chosen his action plan, let's just wait and see what he comes back with rather than unintentionally encouraging another change in direction when things are already unstable.
. I never feed my corals - except when I still up stuff when I fill the sump with fresh water. Its good that your ammonia on the badge is stable. I never test for ammonia - so I'm not an expert - I dont remember whether Prime affects the badge (if so - I believe it affects it less so than others). Just wanted to add - the lower the pH - the less toxic ammonia becomes (no im not recommending that you lower your pH - just a comment that at lower pH - the less toxic form is more prevalent). Let us know how its going
