How do fluval light colors correspond to wavelenths
This is the best forum! (besides the ones that help me fix my dishwasher every 6 months) I appreciate all the info on wavelengths/chlorophyll types, etc but I am not understanding what wavelengths translate into the Fluval lighting 'colors'. Anybody know what I am talking about? I am trying to optimize my use of the Fluval freshwater 2.0 light for my 29 gal heavily planted tank that has: angel, glolite/xray tetras, clown loach, new pair of golden wonder killifish, bristlenose pleco and otocinclus. I use DIY CO2 at 2-3 bubbles/second. I want to optimize growth of plants (swords, lotus, java ferns, vals, ludwigia and anubia) and showoff the fish colors. I seem to get a lot of diatom coating plant leaves and some hair algae.
The Fluval light colors that I can adjust percentages on are, in the order given by Fluval: Pink, Blue, Cold White, Pure White, Warm White. Fluval includes 3 different Presets for Lake Malawi, Tropical River and Planted tanks. The 'Planted' has presets of max percentage of the colors at: Pink 84%, Blue 20, Cold White 73, Pure White 100, Warm White 80. I adjusted this to showoff more of the fishes color by adding more Blue 25% and Coldwhite 80%. (I also follow the preset 'Planted' recommendaton to have a 1hour period of low/no light in order to interrupt the algae production.) But i am guessing on what % to set and why? Besides the wavelength=color question, any suggestions?
