Please select the Royal Mail 48 option or contact us for special shipping What Tubes should I order? 2 x 6500K White Choose this for a standard tropical tank. 2 x 10000K White Choose for heavily planted freshwater tanks and Reef tanks without growing corals. 1 x 10000K White and 1 x Blue Actinic Choose for reef tanks with corals Some people also choose this combination for purely aesthetic reasons on both fresh water and reef tanks as the blue light tones down the starkness of the 10000K white. More details on the 3 tube types. 6500K White is a normal general purpose Fresh Water tube and give the best colour balance for every day use. It emulates daylight on slightly overcast day. It gives reasonable plant growth except for the very hard to grow varieties 10000K is a Plant Growing tube. It gives the effect of a clear sky tropical day. It gives the best plant growth, especially in the “difficult to grow” types but is quite “stark” and tends to make the fish look a bit washed out. Blue Actinic is a special tube developed for Marine tanks that gives all its light in the 400nm-450nm wave band, that is the blue light wavelength. They are high output and are not “moonlight” tubes to emulate dawn and dusk. Actinic fills in a small gap in the spectrum of the 10000K tube needed for growing deeper water corals. It also causes Coral to expand and fluoresce. What does the number mean in the white tubes? The number is a colour temperature and equates to the theoretical light spectrum emitted by a ideal Black Body heated to that temperature in Degrees absolute (or Kelvin hence the K). The higher the colour temperature the more blue the tube emits making the light appear whiter the light, the lower the more yellow it is. Normal Household Florescent tubes, including energy saving tubes have a colour temperature of 3000K (Warm White) to 5000K (Cool white/Daylight)Suitability If you are unsure about the suitability of any item, or how to use it, please ask.
