Just installed pool about 5 days ago and filled with my own water. My alkaline is about 350 ppm and ph is about 7.4. I only plan on having pool open a few more weeks. Should I be concerned about my alkaline numbers? Also should I bother putting in stabilizer this season. I am having friends and family over for swimming in 3 days. As of now the pool looks great, the water is crystal clear. Thanks.
