Is it a must to turn off CO2 when lights out??

Hi,

Is it a must to turn off the CO2 supply when lights out??

What is the consequence if I leave the CO2 supply running at a rate of 0.5bps 24/7.

How to test for CO2 over-dose??

Thanks.

Aqua,

you already posted this in another thread and have some answers there... I am closing this double post.
