Luckily in my first year I have not had to go through the SLAM process. Pool is closed. I enjoy the forum and most questions and the learning process is answered by reading posts occasionally. But I do know that next year I will have to help friends with this problem.
So my question is as follows:
Why does the PH about to be adjusted between 7.2 and 7.5 while SLAMing? I fully understand the reliability tests at higher chlorine levels, etc. I doubt most people would go swimming if they had a green pool unless it was cleared up. Once cleared then the PH can be adjusted accordingly. Does the PH rise while SLAMing? Can the PH just be left alone if it was between 7.4 and 7.8, or could some damage be caused to a Vinyl Liner or plumbing during the process?
