My pool is an outdoor pool with has little bather load. It is in full sun for most of the day and the temperature is around 28c most of the year. The pool store got me to this situation be giving me wrong advice! Not surprising from what I have been reading online. There are lots of fruit trees in the yard and I am frequently cleaning the filter and vacuuming. Is aerateing the only way to raise the ph? Thanks for your help!

However, your hardness is awfully high, and your stabilizer is way, way too high for an indoor pool. If the pool is truly indoors, and not exposed to light and has little bather load . . . then your high chlorine use is quite possibly a result of heavy biofilm infestation somewhere in the pipes, filter, or pool. With a stabilizer > 150 ppm, it's going to take extraordinarily high levels of chlorine to clean up.
