Marble dusting a pool, otherwise known as plastering your pool, should be done by a professional, so please call a proffesional to do it for you as you need it to be done right.
I spent many years in the pool business doing repairs. The only reference I have heard concerning marble was the use of marble dust in the plaster mix, both a fine and large grit used. Hope this helps.
Marcite is a "plaster" made from marble dust and white cement. It's put on top of the gunite and gives the pool a smooth finish and bright luster.
dust is not mixed in marble and cement mixture.

To make gesso using marble dust, mix the dust with water and a binding agent like glue or acrylic medium until you achieve a smooth paste. Apply the mixture to your surface and let it dry before painting.
Marble plaster typically consists of slaked lime, marble dust or powder, pigment, and water. These ingredients are mixed together to create a smooth, durable, and decorative plaster finish that resembles the look of real marble.
Algae
Marble itself is not toxic. However, when cutting or grinding it, the dust can be damaging to the lungs. It should always be done using water and proper ventilation.
there is a product called "pebble tec" that is great. better than both products you mentioned. it is a little more expensive, but looks and lasts much better. other wise i would stay with plaster. from what i understand it adhears better to the gunite.
To re-marsite a pool, begin by draining the pool and thoroughly cleaning the surface to remove debris, algae, and old plaster. Next, repair any cracks or damage in the concrete structure. Once the surface is prepared, mix the marcite (a mixture of white cement and marble dust) according to the manufacturer's instructions, then apply it evenly with a trowel, ensuring smoothness and consistency. Finally, allow it to cure properly before refilling the pool with water.
