let tap water sit overnight or not? Is there a big difference/necessary?

Hello all,

Any help really appreciated! I ask this because its alot easier to add with water hose rather than try and pour 15 gallons into other resevouior. My ph out of tap reads 7.7 couldn't I just ph adjust water each time after filling my resevouir? Happy Holidays to all!

chlorine itself will evaporate but, most municipalities use chlorimide, wich is chlorine bonded to ammonia. this will not evaporate....peace

Anecdotal evidence from me says municipal tap water is just fine right out of the tap. If you're using a recirculating reservoir anyway, all the chlorine that can evaporate is gone by the next day. I personally feel like the chlorine helps with pathogen control.

no need to adjust ph of your water,the chlorine will evaporate with in 24 hours after it comes out of your tap.
