I have a canopy over my 120g and right now I have MH lights but I'm upgrading, as soon as it's delivered, to a kessil. Will I need to keep the fan once I install the new light or can I get rid of it?

[/QUOTE]I was wondering about that. I also thought about co2 exchange. Would it be beneficial to keep air flow so co2 wont build up inside the canopy?[/QUOTE][QUOT"Salty1962, post: 2881788, member: 50463"]You may want to keep one going to keep the moisture out of your hood. JAO
I like to keep two big fans in my canopy one pulling air out and one pushing air in. I have found it aids in keeping stable ph while the tank is doing its surface gas exchange from the waves. Nothing wrong with having some flow within a closed canopy i would say keep them. you could alway put them on an apex controller if the heat ever got to high they would kick on and help stabilize the temperature.I have a canopy over my 120g and right now I have MH lights but I'm upgrading, as soon as it's delivered, to a kessil.
