Your numbers look fine. The only thing I am wondering about is your CYA. Does your SWCG manual not call for a higher reading than that?

Can't remember if we suggested this to you previously and don't have time right now to rescan the whole thread to find out but...... just use a 10mL sample instead of a 25mL one. It will make your testing reagents last longer. You'll multiply by 0.5 instead of 0.2.

Did you disconnect the copper electrode to your SWCG?
