Im moving to a new city that uses Choramine instead of Chlorine. I understand that choramine is a combo of chlorine and ammonia. Does anything different need to be done to protect my fish from Choramine?

For Water changes, I fill the tank up with tap water and prime the entire tank while its filling back up. Can i continue you do that? I assume the prime will detoxify the ammonia for 48 hours and allow my beneficial bacteria to eat up the ammonia in that time frame???

Anything else or any tips on choramine?

My tap water P's: .25-.5 ammonia, 7.8ph, haven't tested it yet but city says nitrate of 1ppm.

Thanks!
 
I came from a city that uses chloramine, and prime will work fine to neutralize the chlorine part of the molecule.
Chloramine doesn't dissipate just by sitting overnight like chlorine does though, but in many cases the water utility can use less chloramine than chlorine alone. The average dosage of chloramine for my former city was 1,25-1.5mg/L.
There is normally a 4 part chlorine to 1 part ammonia ratio combination to create chloramine as it leaves a water utility, and likely the reason your tap tests at a 0,2ish level of ammonia, about the same as mine was.
The good part for you a human, is that chloramine does not create as many carcinogenic by products (trihalomethane)as the use of chlorine alone.
