aid will always wear away at the lime in the cement of a pool, however if you are carefully to clean and rinse the acid of fairly quickly it should be no problem. it certainly does a god job of cleaning it.
Age doesn't really matter, as long as the pool is gunite or concrete. But never acid wash a fiberglass pool, or a fiberglass lining in a gunite or concrete pool. I suppose I should explain why, because so few pool pro's understand fiberglass, you will probably receive considerable conflicting information. The finish coat on all fiberglass pools manufactured in a factory is swimming pool gel coat. Unfortunately, this is not true of all fiberglass linings in gunite and concrete pools, although it should be. Gel coat is non-porous which is why it's such a fantastic finish, at least for the first 18-20 years, after which it becomes porous and must be removed and replaced. Using muriatic acid on non-porous gel coat will cause it to become porous, at which time it becomes worthless, and must be removed then replaced with new gel coat. Once it's replaced, you're good for another 18-20 years, unless muriatic acid is again used. -Bill
No. Do not leave you pool empty during the winter. Numerous problems are caued by draining the pool and leaving it empty. The best way I can think of to answer your question is with this "Disclaimer" we have to use.

Yes. Plaster will not stick to paint. You must sandblast off all the old paint plus any loose plaster under the paint. Surface preperation is the key to any good paint or plaster job. Bill Soukup President Commercial Pool & Spa Supplies Inc.
With a new pool surface installed- Diamond Brite or any aggregate surface- is it possible or doable to acid wash the pool with water in the pool??
Turn the pool upside-down and knock on the bottom.
rain and acid wash
Pump out the pool. Pressure wash the pool interior, remove debris. Finish with an acid wash. Check all plumbing for damage etc. Change out the sand in the sand filter (if fitted) Clean all skimmers and leaf filters at the pump and the pool. Fill pool and adjust it chemically after 24hours with pump running.
Poor water chemistry. Ph and or total alkalinity were not maintained. You have calcium deposits or scale as it is sometimes called. Possibly a light acid wash at the start of the season done by a professional.
You risk damage to the car's paint.
Drain, pressure wash, and acid Wash the pool. If the plaster is old, it should be resurfaced. Resurfacing the pool will give you a new warranty and a longer life on your pool.
Use a 10% solution of pool acid and wash with water
Sounds as if you did not filter the pool water for at least 24 hours before adding chlorine. You also may have added too much chlorine at one time. That brown is iron and if you did not react to it immediately it will most likely be somewhat perminant. If pool is plaster a light acid wash will usually correct. The acid wash can be done in two ways; with the water in the pool, sometimes called a no drain acid wash or pump out water and acid wash in the regular manner. Must be professionally done. Sorry to hear of you rmisfortune. Ken
