@Ahultin Thanks for the very useful data. We are having 5 days in the mid-70s in San Diego now so I added CYA and heated the pool to 80 degrees. I'm glad this forum caught me before I added calcium, because it costs about $700 to refill my pool. pH is back up to 7.8 again and I am keeping the...

Thanks for the replies. I subscribed to the premium PoolMath app so I could get unlimited cloud log storage. After adding the soda ash I have the pH and CSI back in range. Of course the TA crept up to 90 as AJW22 alluded to. I measure pH using an ORAPXI 7 in 1 digital meter. It says the salt...

If your new Pebble Tec is like mine you will indeed find a lot of loose pebbles and sand for the first few months. Be sure to weekly (or more) brush the walls and anywhere the robot vacuum cannot easily reach to a place where the robot (or a manual vacuum attachment) can easily reach. You may...

Thanks for the replies! I have posted 6 more pictures in the Introduce Yourself thread showing equipment details and water clarity (and the turtle mosaics). I am currently adjusting the TA downward and the FC upward to get into the ranges that you suggested. Due to the watertight cover and the...

Thanks, I added the equipment details pictures. Between that and my signature it is fairly complete, although the builder was not good about giving me manuals and detailed parts lists.
