from research, plant needs the red and blue spectrum of the light to photosynthesize. According to Groiler Encyclopedia, "Certain wave lengths of red and blue light are the most effective in photosynthesis".
refer to the science project of this cute gal... so white light must have the red and and blue component... so the standard off the shelve Light tube will be enough for planted tank. Used to have a set of light Tri-phorphous meant for planting, they are pinkish that is similar to arcadia tropical tube. http://www.arcadia-uk.info/product.p...n=en&sub=&id=4 |

You can invest in a set low power LED night light... If you want to see your fishes anytime day or night. or DIY a set, it will cost you something near to a set of 2ft light. or just install another set of a small light for viewing only.
24hrs light on is not healthy for your plants, fishes (as mention by many bro) and most important it is not healthy for YOUR pocket... Spending money and yet doing more harm then good is the worst deal. |

Thanks for all the advices guys! Think I will call up Qian Hu and ask them to deliver white tubes instead for my replacement set (they delivered a partially faulty lighting set using pink lights).
However, having read the link provided by Limsteel, Quote:
The_Rock, Ya was a little resistance to using auto timer 'cos afraid I might become lazy with all the automation stuff. But since the timing of switching on/off the lights doesn't tally with my lifestyle, the auto timer is a must now. Should I get it from an electrical shop or an aquarium shop? Thanks again to all of you who helped~ |

Any good LFS shop will sell but they tend to not carry too many different types of timers. Go to those home electrical stores, they have a deep assortment of timers available, be it digital or analog. Go through what you like and fits your budget.
Pink lights will still support growth, just that its not as good as normal white lights. If you insist on your pink lights its fine I guess, just that your plants might grow slower though I never used any pink lights before to verify this. -Calvin |

10-12 hours a day of photoperiod is essential for plants to grow well. The order of lighting doesn't matter as long as they get to photosynthesis for at least 10-12 hours per day. However, it is your faunas(fish and other livestocks) that will be stressed if your tank is exposed to light 24/7. You need to sleep, so do the faunas/fishes(although they cannot close their eyes).

The purpose of using white light will encourage better photosynthesis of plants and thus able to flourish better than using pink light. |

Thanks again for the tips.
Just called Qian Hu and they have agreed to replace our pink lights with white ones tomorrow. They said the salesman who recommended me the lights must have confused with my intentions. Hope nothing goes wrong this time... |

24hrs will it be stressful for the plant?? And for it to operate 24hrs will there be obvious increase in the electricity bill??? Just some thoughts of mine.
