    Yes :) In fact, it will grow better under actinics than it would under "daylight" bulbs.

    coralline don't have a need for much light, in fact water parameters do "fact"
    and if you are cycling now, that could take quite some time.

    Its the best light to grow it under but it has to be true 420nm not the purple 460 many new guys like to use.. Thats about a total waste of glass and gas the 460nm purple lamps.. Coralline always starts out low in the tank where the shadows are..I myself would not think about adding a coral or another fish other then the cycle fish until I see coralline growth its the best barometer of a new tanks health and readiness for a more demanding life form .

    y is it that when i see 420nm it looks soo purple, I run 460nm and it looks way more blue then the 420, Why is this tangster, you say 420 is bluer, almost every time is a a 420nm bulb it looks girly purple

    Coraline seems to like dim light. Ever since upgrading from PCs to T5s my coraline has lightened considerably. I found that coraline seems to also enjoy next to no light. If I move a rock off of another rock it is inevitably completely purple where the rock was blocking the light.

    460 is the purple looking stuff and again spectrum run the gamete from manufacturer to manufacturer a 100% Blue Spectrum lamp Peaks at 420NM this is why I would only us a UVL lamp over any others they use the best earth phosphors going and always a true solid color bulbs But with a true actinic 420 nm is blue not purple that is a cheap bulb or labeled wrong thats 460 really. I totally see no need for that one ..
