The pink-colored film or ring frequently seen on showers, tubs, toilets and pet water bowls is typically caused by growth of the airborne bacteria Serratia marcesens. This harmless nuisance organism reacts with standing water and frequently forms during spring and summer months.
In brief: No testing needed. Conjunctivitis, aka pink-eye, is referred to acute superficial infection of the eye(s), either viral or bacterial cause. Viral infection typically produces redness, watery eyes and does not need treatment except for herpes. Bacterial pink-eye causes redness and purulent discharge (puss), often matting the lids/lashes together in the am or after long nap. Consult doc if you have it. Good luck.
