SRC Member shoelevy Posted January 9, 2005 SRC Member Share Posted January 9, 2005 wat u mean by true colours? true meaning same as wen u see them in the ocean? if so then 6.5k is for u but if u like the blueish of the ocean...20kk is for u if u wan a mix of growth and natural colours...14kk is for u frankly...since u not using actinic...some colours brought on by blue will not be shown vividly if u use 6.5k or 14k so if u ask me...i'd recommend u 20kk Quote Link to comment Share on other sites More sharing options...

Will it cook the SPS and clams? Quote Link to comment Share on other sites More sharing options...

Achilles Tang Posted January 9, 2005 Share Posted January 9, 2005 The choice of the colour of the bulb should not be confused with visual aesthetics but should be tied in with the characteristics of the bulb in terms of the PAR, wattage and colour spectrum. But simply, the lower k bulbs have higher PAR than the higher k bulbs, are usually much cheaper but at the expense of being yellow and hence uglier to the human eye... but corals & clams love them more in terms as they are pretty similar to the Sun's rays that reach them after penetrating a few feet of water, which changes light properties. The higher k bulbs are visually more pleasant but are usually dimmer and therefore necessitate going up in terms of wattage to give enough PAR. I used a mixture of 4 x 400w of 6500k and 20k... and they pack both punch and looks... my SPS corals retain very strong colours and growth under them.

SRC Member ervine Posted January 9, 2005 SRC Member Share Posted January 9, 2005 Alternatively u can have a lower K MH bulb coupled with blue T5s... for me strangely I have a 20k MH with 10k T5s.... For me, I can see marked improvements in coral growth and colours after addition of the T5s... Quote Link to comment Share on other sites More sharing options...
