You only need to change the water in your swimming pool when the chemical tests that you should be performing come up bad. Also, common sense is a factor- if your pool is dirty or has loads of bugs or moss, than clean, new water would be great.
In large pools, it's more common to continuously pump the water out, through a filter, and back into the pool as opposed to being "changed" per se.
Chemical treatments are often added to the water at the same time to prevent/slow the growth of algae.
Yes The 1st response was "YES". Okay. Now why?? If all your water readings are within limits, the water is clear and clean...then why change it?
With the correct chemicals and circulation,the water should never need to be replaced.
With proper chemicals, equipment, and a filter, you will never need to completely replace the water in a pool.

Yes you can (re-plaster) There should be a company in your area that does the plaster for pools when they are built and also re-plaster as they get older. Your Pool supplier should be able to suggest who may be the most reliable. yes,

You have lost the integrity of the plaster for one.
Gypsum heated to remove moisture and ground into a powder is called Plaster of Paris.
The substrate a canvas plaster board ground is the term you are searching for if you are in an art class
A metal Surface being ground is a physical change, not a chemical change.
If you mean ground flour, then no. Grinding flour is a physical change because there is no change in chemical composition.
Yes. Suggest you inspect pool and drain closely for cracks or other damage.
Not really, you've gone this far in your construction phase, why not sit tight and wait for the pool to be ready for plaster. The wet weeping will make the plaster not adhere and you could get plaster pockets away from the gunite wall. Remember the plaster does two jobs, it keeps ground water out and pool water in. You need to make sure that the plaster is applied under optimum conditions. This is not a tactic to not plaster your pool, it is a preventative measure to reduce problematic conditions in the future. You have to wait until the ground water is not coming in. This might mean waiting for weeks for dry weather. If it is next to a lake or something maybe they could put drainage in to drain the area prior to the water getting into the gunite wall, but this is extreme, it means more excavation around a pool that already has a finished deck. Waiting for the weeper to give up is more effective.
No, the ground wire is there for safety reasons and only carries current in fault conditions.
No. That is a physical change.
