I just picked up a (slightly used) Polaris AutoClear Plus SWG which I'm installing this weekend and I just found this site, I think it's going to be a great source. I already have a question (of course):
In the SWG owners manual it has a paragraph that states:
"When sodium bromide is used, it is in addition to the required sodium chloride levels. Refer to the sodium bromide requirements chart in the Reference section."
And it has a table showing how much sodium bromide to add. But nowhere in it does it say that I MUST use sodium bromide or what it's for. I've not seen anything about sodium bromide before in the reading I've done about SWGs. Is this something I must or should add? What's it for?
FYI, I'm in the Phoenix area (hot), and have a 30,000 gallon in-ground fiberglass pool with a 36sqft DE filter and 1hp pump.
