just finished AA treatment for metal stains on fiberglass. treatment worked great. i added the AA
yesterday followed by sequestrant. it has been 24 hours , so i just checked TA and ph. ph was at 7.2, so i will
leave that where it is. TA was 70, so i added baking soda per calculator to raise to 80. of course chlorine was at 0. My question is at what rate should i bring chlorine back up as the procedure says to bring it up slowly?
