Piping for Uber sterilizer

[Roger23]

Sto I’m fairly new to reefing,I have a 7225 peninsula coming on Saturday,I need to get piping for my uv sterilizer from hrs,what size should I use I was thinking half inch

My opinion is this should depend on the size UV you use... I have 2 systems with the Lifeguard 55w and I prefer 1" in and out with a gate valve to control flow so I can change it's purpose when desired.
