Aquascaping Answers: CFL Wattage
Each week in Aquascaping Answers, I do my best answering your aquascaping and aquascaping related questions. Just leave your question in the comments section!
Only one question left over from last week, which I missed due to being sick. Make sure to leave me some more questions in the comments for next week!
Just one last question on using CF screw in type light bulbs - on the packaging, they give two wattage ratings, the actual usage and the equivalent incandescent wattage. Which one do I refer to? I don't want so much wattage in my little 29G tank that I have uncontrollable algae blooms!
This is confusing and is really misleading. The actual usage is the one you are interested in. You can basically throw out the "incandescent equivalent" numbers because they are meaningless. For a 29 gallon tank, I'd stick with between 60 and 100 watts of light (2-3 watts per gallon). Screw in CFL bulbs are not quite as efficient as long CLF bulbs, so take the wattage numbers with a grain of salt. They also create quite a bit of heat at higher wattages so be sure they are well ventilated. Excessive heat will shorten the bulb life.
Ask a question about aquascaping, keeping aquatic plants, plant-friendly fish, lighting, CO2, fertilizing, or any other aquarium plant related question in the comments to this post, and I'll answer them in next week's edition.
