My pool has limescale buildup all around the rim (waterline). In the past I paid somebody to bead-blast it off. This time around, it occurs to me that I can buy the equipment and do the job myself for the same $$$, and the blasting equipment will be there for future treatments and other uses. Can anyone give me any tips (type/size of glass beads to use, air pressure, likely bead usage rate, how to clean the beads out of the pool afterwards etc.) ? Oh, and my pool is mostly PebbleTec, but with some tiles. The scale is deposited on both surface types.
Thanks in advance for any advice you can give me.
