Testing my tap water pH

[Rangeball]

Mine is 7.2 with a .5 TC.

Alk is >300

Just tested some more...

CC 2.2
FC 0.6

Why does tap water have more chloramines than the pool? Where does all the combined chlorine in the pool disappear to?

Many municipalities add ammonia with the chlorine used to sanitize water to prevent the formaton of trihalomethans like chloroform, which are suspected carcinogenics. This addition of ammonia favors the formation of monochloramine. When you shock your pool you destroy the choramines.

So adding chlorine gets rid of the chloramines. What are the products of this reaction?

You got me interested so I tested my tap water. Rural water system
TC 0
Ph 6.8 or lower since it was a lighter color than the 6.8 reading

So my tap water is low Ph and has no chlorine? That may be good since my pool Ph is always high (SWG)

I tried looking this up. I think chlorine plus chloramine yields chloride plus nitrogen gas.

In the simple view, yes....A+ in the chemistry. It's actually a bit more complicated than that but for our puposes it's more than enough. This is what happens (or is supposed to happen) when we shock our pools. Chorine/ammonia bonds are broken to release the ammoia compounds out of the chloramines (CC) and then the ammonia compounds are oxidized (burned off) and release nigrogen gas. The used up chlorine becomes chloride ions in the water.
