You are correct I looked up the city water company's quarterly reports and it is chloromine. Apparently that's much more common than chlorine now days, and chloromine takes weeks to disapate so it must be treated.I have to ask are you sure it's chlorine and not chloramine in your town water? There is ways to run a drip straight into the tank and build your own filter system for it
Thank you everyone who has replied! I'll look into prime and seachem a little more.
