Large Refugium Users

[MediaOne]

Okay, so I am running a 50 gallon refugium on a 90 gallon fish only. I have 10 fish in the tank. I wouldn't say that I have a very large bio load, I think I am far from what my system can handle.

Anyway, I can see that *some* (about 3%) of the algae in my refugium has gone transparent, it didn't dissapear or anything like that... but, what do you think is happening?

1) Is it being blocked from light by other Caulerpa growing above it?
2) This is the first time I have even had to harvest any algae, do you think that it has just grown to its max and I need to learn that where it has grown to now is where I have to keep it harvested.

Anyone else experience this?

The refugium is lit 24/7.

Thanks, Cheers!

You may want to check out a thread form the Kent University. They claim that a 24/7 Photopereod may be bad, and may encourage the kind of observation you detail. I have heard people who have run 24/7 lighting pereods successfully for great lengths of time. So dont presume its that straight away. I have heard people describe similar observations in Celurpa just before it goes sexual. Hope it all turns out well.
