Good Morning Gents. I have to SLAM my pool due to high CC and next to zero FC. I’m pretty new to the pool scene being my second year with a pool and have tried to shock and oxidize to get rid of CC and that hasn’t worked so reading threads here it seems like I’m dealing with ammonia and need to slam the pool. MY Question is we are expecting 5 days of continuous rain here in Northeastern PA and was wondering if I SLAM the pool water today would the constant rain effect that process or should I wait till next week after all the rain. I believe I am dealing with ammonia in the water. I have a TP-100 on the way I ordered last night. Pool store tested water and FC was .4 and CC was 4.8. Thanks for your input!!
