Hello. I have been reading and researching for months but the handoff of chemical balancing from our PB was less formal and obvious than I thought it would be so I have no chemicals on hand. We have a Pebble Sheen finish and I did a quick PH test last night and I think we are nearing 8.0. Our pump schedule was set by our PB and the spa overflow and the bubbler are running about 12 hours a day. I don't have pool school until Tuesday so I have no idea how to adjust those settings. I won't be home without extreme effort prior to the pump shutting off tonight. Am I okay to grab muriatic acid tomorrow morning or should I be making that extreme effort to get some in there tonight before the pump shuts off? Thank you!!
