Cyano Outbreak

HotRocks · Feb 12, 2018

What do you all suggest is best for cyano? I had almost gotten rid of it. My tank has been set up since around 11/20/17, and I just added my first batch of fish 2 weeks ago as they came out of QT. Cyano is going crazy, I'm guessing the fish waste is fueling the bacteria. I am running oversized skimmer ASM G4+ on a RSR 750XXL. Should I dose Chemiclean or just wait it out?

I would chemiclean, I chose the "wait it out" option and it just never happened after months.

For me I did water changes like crazy and reduced my feeding. I’ve also gone to using nopox every other day. Took a little while but it’s now under control

Are you sure it is Cyano? Also, I have read some strains of Cyano aren't cured by Chemclean. I think you can do a search on R2R for details.

I would look at your water and work on your nutrient export. I know you are running an oversized skimmer... but that wont cure all ills for nutrients. Look at some other mediations... such as algae scrubber... or a chaeto reactor. These both do a nice job of nutrient export.... but they are not so efficient to totally strip the water if you were to over do it. I prefer this avenue over dosing solutions like NoPox.... my preference perhaps.

Once you can fix the reason you have an outbreak, then simply siphoning the cyano out and doing water changes will remove it from your tank.

Good Luck.

I’ve seen the tank, it’s definjtely Cyano. He runs enough carbon, GFO, and skimming for 3 750XXL.

Chaeto is a good idea but we keep killing it in quarantine, haha!

If I ever add chaeto it will be a reactor only for me. Tooooooo messy otherwise. But yes definitely cyano. Just trying to make sure chemiclean isn't risky to use. As long as everyone says its safe for all my fish and coral I'm going to dose it. It came from Amazon today. I am so sick of looking at the cyano!

Anything is a risk but I’d say it’s a low risk, personally.

Chemiclean dosed tonight! Hopefully 48 hours and BAM, gone! Thanks for the help guys!

How did it go after the Chemiclean?

Definitely killed off all cyano. I have some coral that's a bit angry. It definitely ticked off my urchins too. Nems and fish didn't care. Coral seems to be on the uphill now. Urchins are questionable. May lose 2 of my 4.

I know this is an old thread but I just came across it looking for a cyano solution. Did your urchins live? I have cyano as well as hair algae. Been dosing vibrant and the hair appears to be getting better but the cyano is getting pretty bad. I have two tuxedos and a long spine and various shrimp, crabs, and snails. Been thinking of dosing chemiclean but don’t want to kill anything besides the cyano in the process. How did it go?

I actually figured out my problem. Chemiclean did not do anything negative, as far as I can tell. My kids messed with my refractometer and it was way out of calibration . So when I did the water change after chemiclean, The water I added was way low on salinity. My longspine urchins are growing spines again. My fish are all good. My coral banded and fire shrimp somehow survived the major swings in salinity!

Oh wow! Glad everything survived! Also glad to hear the chemiclean didn’t seem to hurt. Think I’ll give that a try! Thank you for the response.
