If it is under water, it is most likely a build up of alkalinity. An acid wash will be necessary to remove it. Pebble Tec does not recommend an acid wash because there is the potential for loosening the pebbles. But there is no other alternative except replacing the Pebble Tec. Shop around for a person that is experienced with acid washing Pebble Tec. Maybe ask your friends or a pool store for recommendations. If tech is careful, your pool should be fine. If you have a white line around the top of the water (either on tile or the Pebble Tec itself), that will be a calcium buildup. Pebble Tec recommends professional cleaning with magneseium sulfate (brand name MaxxStrip). They do not endorse using glass beads.
No. Pebble Tec is usually damaged at rolls in the surface such as at a step or on the bond beam. Never heard of chemicals causing cracks.
Pebble Technology, Inc. is the original pebble pool interior finish, started in the US over 20 years ago. There are over a dozen knock-offs on the market today, but none with the quality control, ongoing training, or level of experience as a Pebble Tec(r) applicator. There are approximately 55 companies licensed to install Pebble Tec/Pebble Sheen/Pebble Fina across the country.
Pebble Tec is an exposed aggregate plaster technique. Pebble Sheen has less exopsed aggregate (smother) Pebble Fina is even smother
Yes there are paints available for pools. I have never heard of a stain for pools though. Pebble surface pools don't "loose" their color. What you may be experiencing is a dull calcium or mineral deposit. Deposits can sometimes be cleaned with an acid wash. If it is very bad it can be blasted off by a tile cleaner.

It's all in the application... Pebble Technology trains and certifies applicators, and no other pool finish does that on a nationwide basis.
First of all have you found the cause? Pebble tec cracks because either it doesn't get a good bond to the shotcrete or the shotcrete is cracking underneath the pebble. Cracks found in pebble tec must be patched with pebble patch or caulking. To perform a patch that you care about blending with the existing pebble takes a great deal of experience. Great results are possible but not likely until you have made several patches. Also one of the common issues with pebble tec cracking is not so much the material,but rather how much pebble tec is applied to a certain area of the pool/spa. For example, pool steps tend to get more material applied on the transition/curveof the step tread and having too much material can cause a delamination after time. Most rolled bond beams being exposed to the outdoor elements will experience bond failure in time. Most cracks can be repaired by the average homeowner with a little bit of handy skills and pebble patch kit.
