Our pool is green and cloudy. We took a sample of water to a pool supply store and we were told that the pool needs to be drained. Is it safe to drain a gunite pool?
First, what was the reason cited for the draining? Second, yes it is safe to drain and refill a gunite pool. You may also consider a partial drain and refill where you pump water out as fresh water is added in, again depending on the reason for the drain and refill and what you are trying to achieve.
