lighting

so..i have a deeper tank than most..and my lighting just seems inadequate to me...i really want it to be bright...but at the same time i want it to be healthy for my fish..so i want to know if ANY type of flourescent light will work? (i.e. kitchen, bath, etc..) or does it need to be special for aquariums...

the brightest i've been able to find is 18,000K and it just doesnt seem bright enough to me, prolly cuz my tank is so deep. any suggestions?

I dont know much about flourescent lighting but you could try some of those fully submersible LED's white and blue ones maybe, that could be cool. I have seen them on ebay loadsa times :D

May have to go with Metal Halide. They are the highest intensity and go up to 20,000k. But you could also try submersible lights.

Yeah that one would probably work. On my aquarium I got two 48" 10,000k from Coralife and it's bright as hell!

How deep is the tank? inches? What is in it? Keep in mind that spectrum of light has a lot to do with it and how it appears to us when we look at it.
If I know a few more details, I can maybe suggest something...

As for getting bright light over something 3 - 4 ft tall, you may end up needing something like metal halide lights, but there, you're going to deal with a lot of heat and they are not cheap to run. In fresh water, that would likely also bring algae issues that could be very difficult to get rid of.
If you can measure the tank, my husband may have some less expensive and more appropriate ideas for you, but he'd need to know the dimensions... length, width, and height.

5700K lighting, things appears more yellow. As you get towards 10000K, the lighting is more nuetral. 18000K, I'm not sure. But if you have fish only, they will not care whether it's 57000K or 18000K, it is only what best appeals to you. Plants will thrive best with anything above 57000K.

MH (Metal Halides) are not necessary for fish only tanks.

Regular kitchen, bathroom flourscent fixtures are not recommended becuase they reflectors are made to spread the lights wide into a room. Aquarium lights are made to direct light downwards. Plust the balast on kitchen/bathroom lights are not made for high humidity areas, such as being above an aquarium.

What you may want to look into is adding additional bulbs. For example, if you have a single flourescent lighting system, you may look into either a double or tripple lighting system.

EDIT: After looking at your signature, I noticed your 47 gallon column aquarium. YOu could add submersible leds, as previously suggested.

Also, zebra danios prefer more length than height.
