Help with a Getting Started with Planted Aquaria talk
At our last fish club meeting, a member proudly described how he had
just put 110 watts over his 20 gallon plant tank, because an LFS employee told him, "The more light, the better." He doesn't have CO2 or dose nutrients-the same fish store told him that "We don't do that in our tanks, and the plants are fine." A few of us tried to explain his mismatch light with nutrients, but he was too excited about his new light kit to hear any of it. So I am writing a talk on "Getting Started with Planted Aquaria," with a focus on picking the right combinations of these important issues. Tom Barr has done a great job recently of describing successful low-light setups, and his Estimative Index method is a great starting point for high-light. I have tried to create one diagram describing the relationship of light, CO2 and nutrients, specifically to show where the "success zones" are. Please take a look: http://www.svas.info/Newsletter/success-zone.html Please note, this is the first draft of the diagram. I am looking for input on the whole concept, and on the shape of the "success zone" itself, and the right values for the vertical and horizontal axes. Or feel free to say the whole thing is wrong! Thank for your help. |

Thank for your help. Well i'm fairly new to the aquarium world, ive just started adding plants and i'm in the process of building my own canopy. one thing i think you should mention is the type of light. if you have 2w/gallon of incandescent i dont think youll have much success. i just bought a combination of flourescents, two cool whites and two 41k 'designer' tubes. i'm hoping it will work better than my one power glow. |

This is a good example of lighting requirements
http://faq.thekrib.com/plant-lighting.html Takes your tanks measurements and multiple by plant requirements then divide by 11 hours gives watts per hour. Measurements in inches heres some more ref with other web pages http://www.cichlidtrios.com/articles...dex.cfm?aID=20 Mike "w" wrote in message news:nhv4c.55234$n17.29092@clgrps13...

Measurements in inches Hmmm... That seems to be a somewhat dubious formula. Working this for my 6' x 2' x 2' (approx. 150gal tank): Surface area = 24" x 72" = 1728 Distance of light source to gravel = 33" Watt hours = 1728 x 33 x 0.18 = 10264 (for moderate to bright light plants) Total watts = 10264 / 11 = 933W (!!!) So, 933W for a 150gal tank, or approx 6W per gallon. We are out by about a factor of 2 here, which is serious. Cheers, Michi. -- Michi Henning Ph: +61 4 1118-2700 ZeroC, Inc. http://www.zeroc.com |
