At opening this season, person at the pool store recommended adding Borate to stabilize pH. I have been using PoolCalc app to control chems with inexpensive household products instead of pool store products and have been very happy. Apparently I did not aggressively lower the pH after the Borax loading and now I have a persistent white film on my serface level tile that is not coming off. Did not notice the surface level film/scale till after a wave of heavy rain that almost crested the pool. Once heavy rains past and adjusted the water level, now persistent film.
Added 1gallon Muriatic Acid based on these results, yesterday. Retesting again tomorrow at pool store and continuing to adjust for pH using Pool Calc. Any other recommendations to clean off film/scum would be greatly appreciated.
