[APD] Re: treating change water

["Tom Wood" <tomwood2 at flash_net>]

Keep in mind that most water treatment plants intentionally drive out most 
of the CO2 in the water in order to reduce corrosion in the pipe system. Our 
water comes out of the tap at pH 9.0, but if it sits for a day in an open 
container it will stabilize by itself at pH 7.6 as it takes on CO2 from the 
atmosphere. Our water is about average in terms of hardness and the commonly 
recommended CO2 bubble rate of one bubble per second per 40 gallons of tank 
water yields a final pH of about 7.0. Test your tapwater pH after it has 
been out of the tap for a while to get a true reading.
