I did go to the Doc after I had my reaction and they were concerned about breathing primarily, which was fine. One thing he said that stood out to me was that. In a Reef Tank there are thousands of proteins, allergens, toxins and items that could cause a reaction.
I now use rubber gloves whenever possible when I am touching corals, critters and working in my tank. I am also very careful about touching my face (i.e. mouth, nose and eyes) when working with the tank.
I now this all sounds like a mother nagging, but it is important to be safe and prudent when dealing with out tanks and the thousands possible things that may harm us or our families.
ok .. off my soapbox
Peace,
John
