Re: [APD] Temperate plants for outdoor tank?

Naw. There should be very little water in the tubing and carbonic acid is a very weak acid and only a smidgeon of CO2 goes towards making carbonic acid, and that's when it's thoroughly dissovled in water.
 
UV and O2 and C)2 do more damage to vinyl and silicone in a much smaller amount of time, measured in years.

Isn't there an issue with carbonic acid and copper tubing?
