After months of prep/painting pool, im preparing to start filling the pool tomorrow and need help balancing along the way. I never owned or balanced a pool before but I'm excited to learn. There's always a 1st for everything. Not sure if i should have posted this topic elsewhere. Im Using a k2006 kit. I tested the water which I'll be using to fill the pool and current reading is alkalinity 140, ph 7.4, calcium 290. I didn't test for metal/Cooper but I bought a bottle of Clorox metal/stain/scale for insurance. I think alkalinity and ph might be good where it's at but I need to bring calcium down to 200? Please provide suggestions. Please keep in mind, it's a PAINTED pool and not replastered. I also have muriatic acid on hand if neeed.
