if the salt water pool has a extreme high mineral content it ,could make the grout white, if the grout is new.
No, salt water in a properly water-balanced pool will not damage grout, tile or concrete around the pool. Damage to such surfaces will come from improperly balanced water that will either scale (deposit onto) or will corrode (pit and dissolve) the calcium carbonate in grout and concrete. Water balance is determined by pH, Total Alkalinity (adjusted for Cyanuric Acid), Calcium Hardness, Temperature, and Total Dissolved Solids (TDS). For more technical info, go to http://www.corrosion-doctors.org/NaturalWaters/Langelier.htm I have a spreadsheet that calculates this and couldn't find a website that did it all right including TDS which for salt pools would make the index about 0.1 higher than reported by a website such as the following: http://www.aquachek.com/calculators.asp?action=lcalculator&CID=4
Grout was not properly mixed. It most likely mixed with to much water. Your water could be aggressive with a low pH attacking the grout and plaster. Test and adjust. If your pH is below 6.8 and has stabilized there your pool plaster should start to look copper color, aqua color, have black stains which look like graying spots. But once the damage is done you can't undo it.
I would say water is safe, balanced and crystal clear.
Removing the tiles and old grout is a dirty and difficult job with the water still in the pool. It has been done. It is just as difficult to install the new tiles & grout. I have of some doing it from inside a small boat in the pool with the water lowered. Have heard of others doing from the deck working up side down, if you will, to set the tiles.
Make sure your chemicals are balanced and add a clarifier available at your pool supply dealer.
No. Assuming the water has been treated/is balanced.
No, salt does not damage the plaster. Improper water balance will.
Not particularly so long as it is properly balanced and sanitised.
You can swim in it when the water is in it and chemicaly balanced.
Then you can't swim
The water in a pool can be cloudy because the chemicals are not balanced. If people wear sunscreen and go in the pool before it has soaked in it can also cause the water to become cloudy.
I don't know, because it is not true the amount of salt that is used in a salt water pool while slightly more corrosive then fresh water (About the same amount of salt as you find in tears) will not cause any appreciable damage to modern pool equipment as it is made for salt water pools, salt water pool being by far the most common pool these days.
You will need a grout saw and grout scraper to remove the old grout. Then use an epoxy grout meant for swimming pool use, and work in small areas at a time. Choose a color that matches the tiles. Follow the mixing instructions on the container. When all the tiles are properly filled wait for it to dry before finishing the job with a sealant.
More and likely yes, the sun would dry the tiles out may cause the grout to pop off, crack,
A pool the water is sanitized and with proper water chemistry. A lake may contain harmful bacteria. Water chemistry in a pool is balanced to somewhat obtain the chemical levels that are present in tap water that you drink. You are trying to duplicate that with pool chemistry. You drink chlorine and wash clothes in it. After hurricanes and such small amounts of bleach is used to sanitize water enough to drink. Think about it. Would you drink that lake water or drink your properly balanced pool water instead? Hope this is helpful.
Yes...any concrete grout will work.....you're better off regrouting though because chances are that the grout is sealed and the stain will only last one or two seasons.
So long as there is water coming through the pump when it is running it doesnt matter what the water level in the pool is.
You can, if the water presently in the pool is 'hard' - but be very careful to keep an eye on the Calcium Hardness of the pool water. If you filled a pool with water from the softener, the water would be hungry for calcium and drag it out of the pool walls, making them feel and look like sandpaper. Calcium hardness should be kept within 200-275ppm. best to use regular water for topup and keep the pool water properly balanced (see your local pool store).
To change a chlorine pool into a saltwater pill, it is important to drain it. From there, you want to wash the pool to get the chlorine residue off. Then, you want to buy new equipment. Add water, then add the salt, but not until the pH is balanced.
Since it is my job to clean off the hard water stains and calcium deposits from pool tile, I'll answer from that perspective. Grout lines are the most difficult part to clean. Since larger tiles have fewer grout lines they are usually easier to clean. My personal preference though is 1" irridescent glass tiles covering the entire pool, for the elegant look.

It comes out because you have not applied it properly. Either it isn't deep enough in the cracks or the mixture is wrong(too much water, too little water)
Not likely, make sure all chemicals are balanced. If still cloudy, use a clarifier sold at pool stores.
Yes, lightning can damage a pool light.
To lay pool tiles, you will need mortar to affix the tiles to the cement pool, you will also need grout for between the tiles and a sponge to clean the tiles.
