An odd phenomena has occured. I tested this morning and my Chlorine is reading 12 ppm after a pretty heavy rain last night. I brought chlorine from 1 to 3 ppm yesterday and I added the maintenance dose of the jack's magic blue yesterday could this have something to do with it?
 
Test again, wiping the tip with a paper towel between drops.
 
I doubt they are brass. I don't think there is a pool fitting maker that would use brass. Bronze is more likely.

Salt with brass can cause de-zincification. However, every form of chlorination ends up adding salt. My pool was 2000ppm when I installed my SWG. Any pool chlorine or salt is a salt pool.

More likely they are bronze. Bronze and salt is not an issue.

I would not worry about it.

@PoolStored Thanks, the pool is probably 50 years old.
