I don't work in the valley... and to protect myself I will not include the location. However, my RCAC, GM, DM, etc would never allow me to use medications besides the ones given... and even then it needed approval (out of the 100's of times I asked for approval I got approval twice). I could not use Formalin, I could not use copper (even when I suggested a test kit to control the dosage, which makes copper extremely safe for almost all saltwater fish). I had to do freshwater dips on almost two dozen fish daily on average to ensure that things would be acceptible for sale, even then I was extremely nervous to sell ANYTHING.
The whole company doesn't understand disease, or acclimation, or even basic husbandry practices... instead of getting better filtration like a good skimmer, we wasted it on snake oil such as "Microb lift," pretending it would kill algae and disease...
