I currently use liquid CO2. My plants have shown growth. It is only the
algae bothering me. I will try changing the bulb. Do you recommend liquid CO2 everyday? Thanks "Elaine T" wrote in message t... Logic316 wrote: Elaine T wrote: Huh? Blue promotes algae, not red. "Too much red light in combination with high nutrients will stimulate algae growth" http://www.algone.com/aquarium_lighting.htm "Green hair algae thrive on more-red spectrum lighting" http://www.syngnathid.org/articles/greenHairAlgae.html I guess some species of algae like the blue spectrum, some like red :-/ Yes, but your articles refer to marine algae. Marine lighting is very different because of the way the ocean filters longer wavelengths out of light. People have posted here that actinics and sometimes 10,000K lighting over FW promote algae growth. Have you looked at how much red and how little blue is in the spectrum of a 5500K bulb? 5500K and 6700K were not chosen arbitrarily. Those are the color temperatures at tropical streams where algae-free FW plants have been collected. http://www.thatfishshop.com/equipment/lighting.htm is a nice little article. http://www.thekrib.com/Plants/Tech/lighting.html has some info on it as well from old work at Phillips and by Dennerle. -- Elaine T __ http://eethomp.com/fish.html '__ rec.aquaria.* FAQ http://faq.thekrib.com |
