New Pebble - first tests

If you Calcium Hardness really is that low, I'd probably use Calcium Hypochlorite to chlorinate your pool for a while to get the calcium up. With your pH that high, several pounds of baking soda probably won't increase the PH much, but will bring the TA up into the ideal range. I'd use Muratic Acid to bring the PH down, but you might want to get some Calcium and Alkalinity in the water before you drop it too much
