My man, you made my day. I understand all your points. We did read all information regarding the treatment and we did it as per book but we still ended up bad. As you say, different brands, different systems. There is not a silver bullet. I did a pile of sample tests and it all worked well on samples.
I will start doing it again but i will pay more attention to detail. I know i sound a bit silly asking this question, but this forum has so many highly qualified specialist. Another opinion is always good
