(3.0-3.5) to (6.0- <br />7.5). Once the pH of 6 - 8 is attained, slowly drain the tank <br />along with water in the second stage to be flushed down the <br />drain. <br /> <br />Checking the pH with a digital, pH meter to insure accurate pH <br />readings should be done while 'draining. <br /> <br />Any questions on the product, please 'call me at 445-4121. <br /> <br />I <br />I <br />I <br />I <br /> <br />Respectfully, <br /> <br />/-I~ONT INDUSTRIES, INC. <br /> <br /> Todd W.
