Hi all
Just an observation and wondering if anyone has noticed the same. I have a UV system and CO2 fully controlled system and I have noticed the plants have taken off since I switched off the co2. Has anyone noticed the same or is aware of the UV affecting the CO2 in any way. I assume it is possible as it alters just about anything else.

Cheers

I cannot imagine the UV having any effect on the CO2... The uv kills water borne organisms, ie. algae and some bacteria... Co2 is a molecule, in a gaseous state (CO2 is unique, in that it does not exist in a liquid state TO MY BEST KNOWLEDGE under normal labratory conditions, perhaps under extreme pressure, dry ice is the best demonstration of CO2's 2 states, rather then 3 in most other cases, when it defrosts it goes SOLID --> GAS with no liquid stage inbetween)

So rationally i cannot see how the uv would affect the co2....
