Last year I had my plaster pool full drain acid washed and the guy did a really crappy job.
You can now see drip lines in the side walls and bucket rings on the bottom. The plaster is very rough in parts. I am also having a **** of a time keeping green alge from growing on the sidewalls. The water is clear but the alge just keeps on coming back. I thought it was because it as a rougher surface to stick to.
Does anyone have any ideas on how to fix this? Do I need to just replaster?
