否則很難給您建議喔!

T5這燈具 做成這樣 不知道要多少錢....................

It depends on what you are keeping of this tank. It would be no problem if you are keeping fish only. Coral needs more light to maintain it's color and growth.

Some times lights might not be the only solution if you are having problems with your tank, even with the brightest HQI lights but without good water condition there is no way you can bring out the best of coral's colors.

Your tank width is a-bit weird...unless is a ultra shallow tank, my tank is only 90cm wide but my water volume is over 250 Liters.
If it's a shallow tank you have, the light fixture on your picture is sufficent for LPS if it's with HO tubes, I would recommand 2 6500K and 2 Actinics/20000K

Not really sure what you are asking here, please be more specific so people on the forum can help you!

P.S. where about in Canada are you from?...I assume you are Chinese but on a non-Chinese input computer...right??

How come a 120cm tank with only 114L water?
What's your tank size?

Can you read tranditional Chinese? it's much easier for us to answer your qyestion in Chinese.
