if you want a reef or to keep any corals you need better lighting. you can probably get away with that for a little while but the more lighting you have the better. if you compare watts to gallons like a lot of people do. you have .4 watts to every gallon. others will run between 4 and 9. id plan on investing in another light

You will HAVE to get better lighting. here is my generic post for lighting...

In reef lighting, people often get PAR, WPG, lumens, and K ratings confused.
WPG, or Watts Per Gallon, does not work. It does not account for the types of bulbs being usedm or the depth of the tank.
The K rating, or degrees Kelvin, is just color that the bulb appears to our eye. The higer the rating, the firther down the spectrum it is. (10,000 K is yellow, while 20,000 K is blue)
Lumens is just the amount of light the bulb putputs according to our eye.
PAR, or Photosynthetically Active Radiation.... is just the measure of the amount of Radiation, or light, capable of producing photosynthesis.. Now it is not the corals themselves that photosynthesize, its the zooxanthellae. Zooxanthellae has a mutualistic relationship with the coral, and lies within the corals tissue. They then photosynethesize, and give the sugars to the coral, and in return, the coral gives the zooxanthellae a safe place to live.

Bulbs and PAR...

there are so many bulbs out there that say they can grow corals. But which ones are truthful?

VHO bulbs. despite all the hype... VHO bulbs are not very good PAR producers, and should only be used as supplemental aesthetic lighting.

PC bulbs. These bulbs, despite all the bashing on them, are useful for growing any coral, until you hit about 25 gallon sizes. 14 biocubes can grow anything. 29's may struggle with SPS, but for the most part, are okay for growing most coral.

T5HO. These are tied with metal halides as far as less than 24" tanks go. beyond that, the PAR level is just too low to grow anything. There are many parts to getting a good T5HO setup.
1. High Output. You cannot just go out to the hardware store and buy a standard T5 setup.

2. INDIVIDUAL reflectors. without good INDIVIDUAL reflectors, highly polished, most of the light will be directed sidways, and out of the tank. drastically reducing the bulb's eficiency, and goral growth. This one of the reasons why I never will order from odyssea. they are just not up to par (pun intended).

3. ballasts. this is a key in both T5HO and halides. without good ballasts, you will strain your bulbs, and shorten life.. reason #2 never to order from odyssea. Before their redesign, they had problems with their ballasts melting and catching fire. Not good.

4. the right bulbs are the KEY. ATI bulbs are the highest PAR producing bulbs, to my knowledge

All of these combined will give you a very nice setup. As well as # of bulbs, but that depends on size of tank..

Metal Halides.
these babies are the probably the oldest runner in this battle. they come in a 2 tie with T5HO. while T5HO may be good for less than 24" tanks, MH can go much further than that with substantial PAR values. At a price.
The sheer wattage levels used to run HM are crazy. While you may get great PAR at the bottom depths of your tank, you will have to run at a minimum of 250 watts, probably 400 PER BULB. Plus they are very high heat producers. But with the right reflectors, and ballasts, you can cover you tank in few bulbs than you could before. But since this technology is very old, we need a new runner for versatile, high performance PAR producing bulb.. this is where LEDs come in.

LEDs rank #1. This is not just from a blown out of proportion hype about them. this is the real deal. LEDs by far produce the most PAR per watt or any bulb, and produce the less heat, and take up the less space. I just completed an experiment on my 15 1 watt LEDs on my tank. The coral grew 4 times as much, and 2 times as fast as with just T5HO. Now the price on LEDs may be high, but with DIY sites such as rapidled.com, are cutting the startup cost in half. there are also some great fixtures from ecoxotic.com and the aqua illuminations SOL LEDs.They also penetrate the furthest. just see this transformation at the Lego land aquarium!

This is just an explanation on all the types of commonly used reef lighting.. please ask questions if i confused you, or if I need to go more in depth!!

-----------------------------------------------------

what you are running is incandescent lighting, which isn't even on the list because it does not produce hardly any PAR.

Now in a 20 gal, you can use PC as your main lighting because the tank is small, and shallow.

yes. That lighting that was posted will work just fine over a 20 gal.
