Any pool Interior finish will dry out and crumble if allowed to do so.
yes
A 10-20% solution of muriatic acid and bristle brush will clean the pebble tech. Be careful, the acid will burn if it comes in contact with skin or eyes. By 10% I mean 1 part acid to 9 parts cold water. Always add acid to water not water to acid due to unwanted thermal reaction.
pebble has volume so water rises equal to volume of pebble
brush it with a strong solution of acid, Becarefull for your eyes ETC and then hose it down.
There is a web link describing quarts finish below. There is also a web link on pebble tech below. pebble tech and quarts are pool surface finishes (see the links mentioned above) Wet edge is a method of constructing a pool where by one or more edges of the pools side are built just below the waters natural surface height. This brings about a situation where water is constantly falling over the edge of the pool into a balance tank and then via filtration back into the pool.
It shouldn't after all the top of the pebble tech pool is out of the water forever and it doesn't seem to hurt it. However be careful that you don't get a build up of ground water around the outside of the pool, This can cause an empty pool to start floating and that will definitely hurt it. If you have a hydro static valve at the bottom that works it should be ok.
because a pebble is denser than water thus making it sink oil is not denser than water.
A pebble thrown in water creates concentric, expanding circular waves.
I doubt it and if it worries you, fill the crack with a cement grout mixture,
Pebble sheen is usually the most expensive per square ft. is smoother than Pebble tec because the size of the pebble is smaller. Pebble tec is close in price to Pebble sheen is not as smooth as sheen but has better longevity because the larger pebbles stay in tact longer. Ultra poz is less expensive than Pebble is smoother than sheen. warranties depend on the company you choose but here in Phoenix I am seeing similar warranties on all three. A smooth surface is easier to clean but a darker color may not show the dirt like a white surface will. The darker the color the warmer the water.
Well, it is possible that your pH and alkalinity have stabilized where they need to be. You did not state your readings. I would have to know those to have a better answer. k
