When the pool's bottom isn't visible, cleaning with chemicals isn't as effective and it usually costs more than the price of acid washing the pool.

The acid wash strips off a thin layer of the plaster. The majority of plaster coats exceed a 1/2-inch measurement. Stripping a bit away isn't harmful to the pool walls, if done with care. It shouldn't be done annually, or re-plastering sooner will be necessary. However, an acid wash can be done several times before re-plastering is required, when done correctly.
