I'm new to the Forum so my apologies for asking questions that may already have been answered somewhere else. I had a question on Cal-Hypo and SLAMing. The chart at:
Pool School - Chlorine / CYA Chart
says that given my CYA of ~60 if I need to SLAM my pool to equalize total chlorine and free chlorine I would need a shock FC level of 24. Given that I am in the Austin Texas area I wonder if keeping CYA around 60 is optimal (feedback is appreciated here but not the primary purpose of my posting). But getting back to Cal-Hypo and this forum thread, is there any impact that needs to be accounted for due to the granular nature of Cal-Hypo possibly causing the concentration of chlorine in the immediate vicinity of granules being significantly (until the granules dissolve) higher than the average chlorine concentration across the pool as a whole? If there is such an impact, does that mean that a smaller dose of Cal-Hypo (or any other form of chlorine that would not rapidly spread its chlorine contribution equally throughout the pool) might be needed to equalize total chlorine and free chlorine than the chart (which I imagine assumes the chlorine source is distributed evenly) recommends? I'd be especially interested in having chem geek or others with similar in-depth engineering-like chemistry knowledge provide their perspective. Could this impact explain some of the anecdotal evidence posted at:
Why do you never recommend Cal-Hypo?
that Cal-Hypo appears to behave differently than liquid bleach at the same nominal level of chlorine addition (apart from increasing CH levels which is well understood already)?
