Hi,
I have a couple questions that I am hoping someone can help me with.
1) I have been Slamming for the past week but now have more green spots on the floor than I had a week ago. The water is still crystal clear, just with green patches on the floor that don’t go away even when I brush them. I have been testing religiously with my TF Pro kit, but am thinking that I was being too strict with the CYA and therefore getting a 40 on the test when it should have been higher. Today I took a sample to my local pool store chain to get a “second opinion” and their machine is saying a CYA of 50 which is closer to what I got this when I wasn’t as strict about the faintest shadow of the black dot disappearing. So I increased the chlorine level appropriately to 20, but am now concerned because my daughter and a friend decided they want to swim on Thursday so I’m not sure how low I should try to let the FC fall before then.
2) I reduced my pH to 7.2 before I started the slam last week, but earlier this week we got a ton of rain and I had to drain the pool a bit to keep the skimmer from overflowing. It ended up going a little too low so I needed to put some fresh water in from the garden hose, approx 2-3 inches worth in an 18’ round pool. Now since that rain and fresh water diluted my pool, do I need to be concerned about swimming in it since I can’t get an accurate pH during a slam? The pool store test today came back at 7.1 but I know that the reading will be off due to the slam.
Thanks,
Jared
