In a nutshell, a no-drain acid wash is lowering the pH level of your pool so that your pool water becomes acidic and alkalinity close to zero.

A nylon or rubber brush is the correct choice for scrubbing the sides of a soft-sided above-ground pool. A large pool brush makes quick work of the job, but you may need a smaller brush to clean corners. Once the particles have been removed from the sides of the pool, turn your filter back on and agitate the water.

Calcium buildup is a white and scaly buildup caused by high pH or alkalinity levels in your pool water. This causes calcium carbonate to separate from the water and stick to the pool tile.
Set up your waste line and vacuum the pool to waste getting the algae and debris out of the pool. Don't let the water level get too low during this process, if it gets more than 6 inches below the tile, stop. Turn the system off and refill the pool and repeat until the whole pool is vacuumed.
