The link you posted is dead.

What Kelvin rating is the Actinic bulb (blue) and the daylight bulb (white)?

There is alot to know about lighting. The PAR, The kelvin or color of the bulb, the intensity or lumens which is how far the light will travel thru the water to reach the bottom of the tank, and then wattage.

The lighting you get also depends on what type of corals you want to keep? LPS,softies,SPS?

Fish dont need light for growth.


Heres some info on lighting.

To be honest youd be able to keep more than softies with that light. Just remember to replace the bulbs on that about every 9 months or so.

But some people said that i can't keep any coral with this light because it's 55 wat like 5000k and for corals i need 10000 so what do u say?

10K you would be fine. I wouldnt use 5K bulbs for a daylight bulb.
