I have been trying to buy a bottle of Excel to experiment with, but it appears that it is now illegal to ship it to California. Even the fish stores here can't deliver it when I order from their websites, nor can Amazon or Ebay. So, I sent a question to a website that sells Metricide 14 to see if it could be shipped to California. Their answer was yes, it can be shipped here. Does anyone know what this is about???
