I just built a new gunite pool. We finished filling with water last night. My pool maintenance guy said not to worry about brushing. The leaves are falling and I put a leave net over the pool. They dumped a few bottles of the Startup Tec chemical into the pool. He said he would rather I leave the net on and not brush, as opposed to pulling off the net and brushing every day. I've read the Pool School topic, so I wanted to get some opinions. Should I ignore his advice and brush?
