CO2 affect temp?

[evolim83]

I was wondering since CO2 is a greenhouse gas, does this properties still

hold valid when CO2 react in our tanks to form Carbonic acid.

If so, i guess this might affect the temp of our water after the photo peroid!

I understand that it is good to pump in CO2 an hour or so before the lights come on, and cut off an hour or so after the lights goes off!

Has any bro here experiment with this and notice any great differences in water temp.???

Thanks!

I read from TFH magazine, With CO2, the temp is lowered ABIT than normal..
