I currently have an eclipse hood that can house two bulbs. The recommemded wattage on the hood is 2 x 18W. I have gone up to 2 x 20W, but am afraid to push it higher.

My lfs guy, (who has been very knowledgable dispite some minor language barrier) suggested I switch out one of my lifeglo bulbs for a 20W actinic blue. He suggested this was a better balance for the plants and fish in my tank, and also said something about it "tricking" the plants into "thinking"they are receiving fuller spectrum. I did put a blue in, but now I am sceptical.

I also started injecting CO2 recently, so I really want to improve my lighting situation. I really want to upgrade for higher wattage, but not sure how easy or even if possible with the eclipse hood. Will I need to get a whole new hood? Or does eclipse sell upgrade kits? Can I just get what I need a my local hard wear store? Obviously I need to do some more research, but would love to hear from anyone who has experience with this, or anyone with ideas/advice in general.

Thanks!
