Cyanobacteria

[markoshark]

As i'm not running an RODI unit, i have a nice red carpet of Cyano coating my sandbed & some of my rocks. What can I use to get rid of it (RODI is my next bonus )

Any other ideas, apart from more skimming (Sorted..), and manual removal (doing)

Just syphon it out / blow it into your skimmer with a syringe.

Just syphon it out

yep thats the way i use to do it comes off really easy

dont dose anything - it will just come back. keep syphoning it out, sort out your nutrient problem, increase water flow, replace old lights.

I've found anecdotally that salifert flatworm exit gets rid of cyano and hair algae.

I'd had hair algae growing probably an inch of depth every day or two on my rocks and covered in thick mats of red cyano. I'd been fighting it for months, massive water changes everything.

Used flatworm exit to kill some flatworms and within a week my rocks were spotless. Never had cyano or hair algae(In any more than traces) again.

Enough of a correllation I'd like to give it a try again to see if it really works. Could be the toxins from the dying flatworms were the cause, kind of like chemotherapy?

That's an interesting one Ira.

Should post that on RC where there's more people and see if anyone else has had the experience and maybe discover if it's the toxins, the FWE, or what.

One thing I know, if somebody would like to become a millionaire, invent an easily used cure for algae in marine aquaria.
