The company is coming out to plaster my pool tomorrow. They say that a technician will not be out until Tuesday to begin brushing and circulating the water with the pump. Until then, I am just to add the sequester liquid to the pool and then just let it sit until Tuesday. What are you guys thoughts about this? Is is okay to not start balancing the water chemistry and brushing it before Tuesday? Any issues that may occur with the plaster if it sits without being brushed over the weekend?
