Cyano resistant to chemiclean

JaimeAdams · Feb 20, 2018

Ok, so I work 6 days a week at a retail saltwater aquarium store, I am the president of the 3 rivers marine aquarium society, past president and other board positions of the Pittsburgh Marine Aquarium Society.... I've been around and solve peoples tank issues every day. People ask about cyan all the time and I'm like here chemiclean, increase aeration, use, boom cyano gone.

Well, I am dealing with cyan that is not responding to chemiclean, even at much higher dosages than instructed to use. I'm really not sure what else to try so figured I would reach out to you fine folks and my friends at #reefsquad anyone got anything for me?

Look at spirulina , also In the cyano family , but usually resistant to chemiclean and also the peroxide test.

Is the Chemiclean fresh? Did it expire, or anything?

Excess nutrients along with depressed NO3 and/or PO4.

How old is the tank?

How large is the tank and what is doing the flow on the tank?

Is this a managed tank or one that gets care every day from the owner?

Having a similar problem. Mine arrived after using a product to kill bryopsis. I've been fighting it for 4 months now. I'll follow along. PS, looks like Cyano under magnification, turns solution pink in the peroxide test, how about yours?

Blue life cyano rx. I used it and it worked great. I documented it in my build thread

Going way out on a limb here but if cyano is treated multiple times with chemiclean could the cyano build a defense so the chemiclean is less effective? Like antibiotics to an infection, makes sense.

ReefQueen · Feb 20, 2018

Well now I know where my annoying cyano came from

. I am about 21 hours in with ultralife red slime remover and the cyano looks way worse then it did last night!
This was right after treatment

This is right now

Looks like even my last resort isn't working lol.

Have you tried a three-day blackout?

I had that work on a troublesome cyano infection . . .

I’m all SPS dominated so I am scared to use chemiclean or blue life cyano rx

I keep mostly sps as well and had no issues with blue life

Like I said I did document a bit on my thread that I posted.

The chemiclean did not bother my SPS at all, I used it at label dosage. It did not kill the cyano either. I have had a bad experience with peroxide before. Might have been other factors but I'm skittish on that protocol.

I have SPS in my tank, will hydrogen peroxide harm it, just want to know if this is safe for tanks with SPS, this is probably my last option of combating this problem.

Peroxide and other full-tank treatments aren't a great solution anyway since it only works in a fraction of cases. (And they aren't that great for the tank overall.)

Unfortunately the cyano test that gets repeated a lot (cyano in peroxide leaking pink) isn't entirely valid.....cyano left alone in saltwater will do that too. (See my post in the twilliard thread if you're really curious.)

Also unfortunately, cyanobacteria has a significant ability to process hydrogen peroxide harmlessly via peroxidase enzymes they produce....the more established the cyano patch, the more capability they have.

Fortunately @taricha figured out a while back that this peroxidase ability could be used as the tell-tale sign. Put the mystery algae in peroxide and see if it bubbles like crazy as the enzyme goes to town. Other algae just poop their pants.

If you're going into your tank with straight peroxide, this is the way to do it most effectively:
Algae Cure!! Spot Treating Algae With Peroxide

Even versus large outbreaks....just use this along with all the other husbandry methods you normally would: correcting water supply issues, manual pulling, scrubbing, siphoning, gravel cleaning, rock blasting, CUC boosting....and peroxide spot treating.

@mcarroll thank you, this will be my last option if my first option does not work, basically just cutting down my supplements and controlling my nutrient issue.

tankstudy · Feb 21, 2018

Using chemiclean try using a higher dosage with a 7 to 14 day treatment plan versus the labeled instructions.

From my own experimentation, a lot of the cyano will actually not start to die till the 2nd day or even later.
