Thank you! I’m on top of this water chemistry. Even though my Alkalinity stays pretty stable ~90-100. My ph goes up from day to day....maybe because of the new plaster.Nice pool. Welcome.
As mentioned previously note the running pressure after cleaning the filter, it will give you a baseline. When pressure increases 20% from your baseline it's time to clean the filter.
Test your water often to learn your chlorine demand and keep you pH in check. Monitor your CSI to keep your pool and tile in good shape for years to come.
Don't add anything to your water unless you know exactly what it is and how it will effect your system.
Also consider putting a hair net over your skimmer basket to keep much of the surface debris from reaching your filter.
