    Yes, the colour - or kelvin rating - matters enormously, whilst corals prefer lower K rated lamps (or natural sunlight) to grow, this makes the water look very yellow and encourages algae growth, aquarists prefer the look of 10,000k or above for a crisper, slightly blue white light.

    If you're planning on keeping corals, you need to replace the T8's with stronger lights eg T5's or metal halides.

    Somehwere on the bulb itself you should see a number with a "K" after it, but as above, you need T5's minimum to help corals survive.
