How much is mineral pool upkeep?

Hi guys,

My sister recently bought a house and she was thinking to add a mineral pool in her backyard because of its benefits and her two athlete sons.

Does anyone know how much the pool upkeep can be for the mineral pool from MagnaPool?

Thank you.

It looks like the MagnaPool is the same as a saltwater pool with a chlorine generator.  Personally, I would recommend a regular saltwater pool with a saltwater chlorine generator for the same experience at a lower cost.
