Friend or foe?

I have a slime on the surface of my refugium that I've never seen before.  If you get grossed out easily, close this topic right now.

It looks like a big blood clot resting on the surface.  It's kind of thick, not viscous.  Reddish-brown in color.  I can skim it with my fingers and take it off.  This is the kind of ooze that I imagine helped form the Earth back in the early protozoan days.  (What happened to that hilarious dinosaur theory?  Some of the newcomers would LOVE it!)

Friend or foe? 

It would look like a sheet of reddish brown ooze.  You've seen really big blood clots?  That's the stuff.  But I can take a picture... it would probably look brown.

agreed... a definite description of cyano. Cure??? Phosphate reduction and/or 24/7 skimmer usage... at least until the cyano shows to be receding.

j's55, I'm sure glad that you "found" the "cure."



Renee is awesome.

I forgot to tell you that I have a few cute single friends in the UK that would just ADORE you.  Do you like an English accent?

I've helped several of them prepare their curriculum vitaes.  I even helped some of them translate them to resumes!     Wait... you're more interested in their work ethics and history than their minds & bods?  Oh, dear.   Do we need more lessons? 

Hello everyone,

This also means that circulation is impeded; ideal conditions for Cyano growth.

I've seen "increase circulation" advice regularly to "treat" cyano. Lately I've been questioning it's effectiveness.

If you put some cyano in a dish and agitate the sample, it will of course dissolve. This obviously does not remove the bacteria from the dish. So now I'm wondering: Is it better to keep the cyano dissolved and invisible or is it better to let it accumulate for manual removal?

Typically I would recommend controlling the accumulation of cyano by controlling imports (light,food,etc). But lately I've been thinking that manually removing the bacteria could be a great way of exporting nutrients.

Hope that helps,
Chris
