hello again. I just set up another hospital tank for my dwarf neon rainbows that are on their last fins . I picked up one of my two battery powered air pumps because my normal one is in use rn. It has battery acid in it and I have no clue what to do because that stuff is dangerous loll it was from a d battery. Now I’m scared im gonna die lol. If anyone can help that would be gR8 thx. Should I throw it out or?
