Unable to see main drain grates from the edge of the pool at the deep end. Unable to reopen due to excessive turbidity and absence of free available chlorine level. Keep pool closed. When ready for inspection to reopen the pool email chrisite.graves@tn.gov. Absence of free available chlorine level. Total chlorine around 10 ppm. Test was performed with my test strip, pic test strip, and dpd test kit. Provide the free available chlorine to be above 0 ppm. Safety equipment is in good repair and easily accessible. Depth markings have been put on coping per code.
