Cyano...

[charlie_g]

Finally getting my cyano prob in check. My question is the few remaining patches I have in my refugium on the macros, if i were to Powerhead it to hell would this just spread the cyano and seed it throughout the tank? Too small to phyphon it out....

If you don't mind the cyano in your sump, I'd just leave it there.

Perhaps, the Caulerpa could be part of the problem. Here's an excerpt from an article that one of the other admins had found.

Coralmania article by Eric Borneman:

In particular, I am very unfond of Caulerpa. It is invasive and very difficult to eradicate. It is toxic to fish and has many metabolites - and releases them when the organism degenerates during spawning. Acidic rhizomes etch carbonate and these algae can kill other more desirable species by overgrowth. I have had it grow right through the stalks of soft corals. Many aquarists say that it has not been a problem for them. My response? Just wait. It will. I guess my big question regarding Caulerpa is why use it at all when so many more desirable species of macroalgae exist, like Chaetomorpha species, or others.
