Just tested calcium again with my TF-100 and I got 800. Here are my complete results. The pool calculator says that the saturation index is .16 which is balanced. But should I be concerned about the calcium? By the way, two pool stores put it closer to 300.
FC 7 (still adjusting the SWG for the Texas summer)
Even though the pool calculator says that the water is balanced, could this be causing the roundish splotches in the Luna Quartz I described in another thread?
