Below are pictures of my pool, and closeups of the various surfaces. I bought this house 2 months ago and along with it the 30 year old pool. Please note, these pictures were taken AFTER I vigorously brushed the surfaces, so it's not algae or dirt. The water is perfectly balanced as I worked on it for the first month diligently and even used RO since we're in a drought.
I would replaster this ASAP, except that the city isn't allowing me to drain and refill my pool, so I guess I'm stuck with the unsightly surface. OR... as I view it, surfaces with character
Closeup of one of the steps. Is that scaling, or bad plaster?
Dark spots / splotches everywhere
And this spot is my "favorite." It looked better before I brushed the PAINT off of it!
The mosaics are the cleanest surfaces!
Please let me know if there are ways to make my pool surfaces nicer looking. I am already assuming I need to replaster everything. I've thought about that technique where you lower ph drastically and brush the surfaces, to even buying that no drain acid washing contraption, but would like your opinions first.
