What is the color temp of aqua colored light?

[loonz]

Recently I was unlucky to introduce a pair of aqua-colored PCs into my tank.Within weeks,the green star polyps bleached,2 finger leathers lost their coloration and my xenia disintegrated and there was rapid growth of cyano on the glass. At first it was something to do with the water but a recent post somewhere said that some inadequate blue lighting could cause undesirable algae bloom.That's where it hit me. The packaging of the bulbs was all in japanese so i didnt understood a word it's saying, it was jus a recommendation from the LFS.The other alternative i had was Coralife actinics,which cost more than twice the ones i had.Guess its quite a big price i had to pay,since i doubt the zooxanthellae lost would come back to the corals.Was there anyone as dumb as me?And does anybody know the color temp of these horrid aqua colored bulbs?

Color Temperature doesn't really apply to blue bulbs--they've got an infinite color temp. Typically, actinic tubes talk about the wavelength of the major output--usually ~420nm.

When replacing tubes, it's best to do them one at a time and worth considering a shortened photoperiod--it's not uncommon that new tubes cause some bleaching.

Thanks for answering.So what is the major wavelength output of these bulbs?Is there a color chart somewhere on the web that i can see?
