R/O Automated Reservoir Build

I’m starting a build for a Revese Osmosis automates Top off reservoir using a float valve.
I want my filtration system to consist of 3 major parts; remove chlorine, sediment, etc./Remove salts (R/O),/ then kill pathogens (UV Filter)

Reservoir- 55 Gallon Water Stoage tank or 125 Gallon Storage tank:

Filtration- Just getting a all-in-one system instead of buying all components individually:
