The Sodapop Logan product is not specifically designed to be compatible with the SodaStar carbonator purchased from Aldi. Here are some key points to consider:

- The Sodapop Logan is a Sodapop brand water aerator, and its accessories are generally compatible with products of the same brand.
- The SodaStar carbonator, although serviced by Sodapop, is a different product and may have its own specifications and accessories.

It is recommended that you check the specifications of the SodaStar carbonator and contact Sodapop customer service to confirm compatibility of accessories.
