I recently had a pool built with an ozonator as my sanitation choice. As part of the package, the builder put in a in-deck auto-chlorinator. Just drop a tab or two in there and let the Ozone do the rest...
Anyway, the pool is only about a month old, and already there is etching coming from the chlorinator outlet. I had my wife's friend come out to look at it. She checked the chemical levels and she said my chlorine was a little low (intentional) but everything else was perfect. She did some research and told me that in-deck chlorinators are not supposed to be used with Ozone systems and you're supposed to use a floater. Supposedly, the chlorine is too concentrated with Ozone when it sits in that thing and slowly leaks into the pool.
Since you guys are my internet go-to guys on pools, I wanted to get your opinion. Are in-deck chlorinators bad for an Ozone pool? If they are, I am going to demand they fix it (and the staining that occurred when they decided to start filling my pool in the middle of a massive dust storm), but I wanted to make sure I had my facts straight before I came at them. If not, why is the chlorine etching down my wall?
