Ok, I have the pool contractor doing a gasket seal replacement and some minor re-plumbing, but I told them I would handle the initial chemical applications. So, I have 10,000+ gallons (only 12x24 pool) of fresh, city tap water in my pool. Once the mechanicals are ready, where should I start? Liquid chlorine (bleach or 12%)? Should I test for PH before doing anything just to see where the city water is? I ordered a Taylor Complete FAS-DPD Pool Water Test Kit K-2006, which shipped today from Amazon, so I hope to have it early next week.
