Re: Bulbs in Coralife CF fixtures

[- <triax at bellsouth_net>]

The actinic is of no use in freshwater planted aquaria, as far as I 
know.  Someone has even gone so far to tell me that it encourages algae 
growth.  When I had a 50/50 CF fixture over my 75 gallon tank (something 
that was encouraged by the know-nothings at the LFS), my water turned pea 
soup green, and algae grew out of control on everything, despite whatever I 
did to curb its growth (water changes, no fertilization, blocking out 
light, cutting back feedings, etc).  As soon as I changed to a 6700K 
daylight bulb, all my problems disappeared.  This was after a 3 1/2 week 
bout with pea-soup water.

Hope this helps...anyone else have thoughts on the matter?
