I just filled my pool up using the garden hose. I don't have the TF-100 yet, but what do you suggest I add right now. I started using liquid chlorine at the end of last summer after using the small round tablets before that. It seemed to help along with the pool caclulater. I know you really need test results to give a real answer, but was hoping some one who used city water could say your CYA will be low. Go ahead and x to get that up, and try to keep your cholorine at x using an OTO test until your TF-100 gets in. I still have some of the old round chlorine tablets if it maters.
I looked for some open pool theads, but all I found were opening it after you closed it for the winter. I didn't see one for fresh fills using city water.
