Aquarium Advice Addict
I have a friend locally that is trying to advise me on setup of my sump, he has stated that I should get a light for my sump and a timer for both lights so that when the tank lights go on the sump lights go out and when the main lights go out then the sump lights come on. His resaoning for this is that with out light the co2 levels rise in the tank (I don't know if this is true or not), and that by having a sump that is lighted alternatly then it will help to stabilize the tank o2 levels. Am I being fed bull? :? 8O
