Thanks Phurst. The green seems to be growing in the same pattern as
coralline, but doesn't look as thick. It may be on the rock, and I can't see it because it blends in, but it shows up well on the black overflow. Is there any studys on if when to change bulbs? I've read both, 6 months and 12 months. Do
MH bulbs need to be changed more frequently than
T5's or visa versa, or are they both about the same?
Thanks, Pam

I have a little of the red velvety algae as well. My mexcan turbos love it. It's never progressed to the point of being a problem, so i haven't really tried all that hard to get rid of it.
It sounds like your bulbs are nearing the end of their useful lives though, and you might want to replace them sooner rather than later. |
