It is not recommended to use saltwater instead of chlorine in a very small above-ground pool. Saltwater pools require a specific salt chlorinator system to generate chlorine from the salt, and these systems are not typically designed for very small pools. Additionally, the salt concentration needed for a saltwater pool can be corrosive to the metal components of a small above-ground pool.
For very small above-ground pools, it is generally recommended to use chlorine tablets or granules as the primary sanitizing agent. These chlorine products are easy to use and maintain, and they do not require any additional equipment.
