I bought a house this past winter and it has an in-ground pool. The former owners used bromine. I have been using chlorine, as guided by the advice on these forums. And the pool water looks and tests fine. Because we are away from the house for 5 days every week, I have had some challenges trying to keep chlorine levels stable during those absences. A couple people on these forums have suggested a salt water generator. As I look into it, some SWG suppliers say you should not use their SWG until bromine levels are very low. I don't want to get a SWG and then screw it up because there's Br in the water.
So my question is how do I know if the Br level is very low? For example, there have been times when my FC level (using the TFT-100's OTO and FAS/DPD reagents) has been undetectable. Am I right that those tests measures both Cl and Br? And if the level was undetectable, does that mean there's no Br in the pool?
Thanks for your help.
