Hi,
I may start to use formalin 37% to qt. new fishes coming in however, as we know, it is a carcinogen and can be bad to breath, touch etc. If I use it in the qt. tank itself do I need to wear a mask or eye protection when I go into that room? Are the vapors or the qt water considered hazardous to people? Or only the concentrated formalin itself?
