Okay, well I'm about to head down to Home Depot in a little while to pick up a couple of 3-packs of their chlorinating liquid. In an earlier post, Dave mentioned that I should reduce the pH to 7.2 before I begin the SLAM process. I have two gallons of muriatic acid. According to the poolmath app, it looks like, at my old pH of 7.6, I'm only gonna need 21 oz of 29% muriatic acid, so it looks like I have plenty. I have a glass measuring cup I'll use for it. I haven't checked pH since I filled the pool, so I don't know exactly where it is now. I will check it in a few minutes. Heck, I might as well do a complete test. I'll report back with my results.
Here's hoping I got my CYA down to an acceptable level. Question, if the CYA is still kinda high, do you recommend I SLAM with the higher numbers, or should I just suck it up and drain off more of the water -- again?
Another question: in the TF-100 test kit, it mentions that it will probably take a little while to get the hang of reading the results -- or words to that effect. I find myself staring down into that turbidity, looking for traces of the black dot, and straining to see it. I'm doing my best guess at it right now. So, I'm wondering if you guys might have any tips about reading this setup to insure more consistent -- and accurate -- results? It would appear to me that this is a number that I want to be sure is accurate since the whole SLAM process sort of hangs on the value I've determined.
