Retrofit Cold Plunge for Automated Chemical Balancing

Job ID: 38139706

Budget: $250 – $750 USD

This is the cold plunge unit I have: https://chillygoattubs.com/products/alpine-terrain-cold-tub
This is the system I want to integrate: https://www.hannainst.com/swimming-pool-and-spa-controller-bl121.html?gad_source=1

Attached is an image of a set up, I am just unsure how to integrate it.

Is this something you can help me do?
