Marie's 175g mixed reef (new pics added jan 27)

Unfortunately, while moving rock around I discovered I once again have red bugs.
I'm in a dilemma, the last time I treated the whole tank with inteceptor, after the second treatment and during the third, I lost over half my acroporas and it took a good 6 months for my tank to recover. Right now my tank is doing great, colours are good, growth and polyp extension are good. I really don't want to treat in case it actually was the inteceptor that crashed my tank...I don't know what to do
