So happy to find this site. It can be a challenge to find the answers to some of my questions. I have an indoor pool that is used year round. It is built as a separate indoor space with a completely separate air handling system but attached to my home. It is a Gunite pool that used to be on is saline system but I found it incredibly challenging to ever keep the water balanced. I love the new nature2 system that I had installed a little over year ago. However, I’m still trying to deal with a couple of vexing problems. I’m so happy to come to a place where there might be somebody with the answer. Thanks so much for creating this site.
