Cyano Scrubber Experiment

AcroporAddict- do you run Chemiclean continuously to keep cyano from re-appearing or do you remove it from the system once cyano disappears?

I've used other chemical treatments for Cyanobacteria in 'fish only' and FOWLR systems and the red slime comes back over time with no new additions IF conditions are right (usually caused by overfeeding and lack of proper skimming).

Hi Gary,
No, I don't run chemiclean continuously as a preventative. Using it as a preventative is wasteful, IMO, especially since I get red cyano so infrequently. I get a cyano outbreak in my two reef tanks (separately, not at the same time) maybe once every 1.5-2 years or so. I just treat per directions and it is done with. But I keep my feeding schedules like I always have post treatment. I have also always followed the same type maintenance regimes, mechanical filtration, good skimming, GAC/GFO, etc, not overfeeding (not underfeeding either), regular water changes, etc.

Any outbreak I have ever had always follows the intro of a new fish or coral. I don't get cyano every time I put something new in my tank, but whenever I do get cyano at the above stated interval, it always follows follows a new introduction to the tank.

What I am saying is that a reef tank either has cyano in it or it does not, and chemical treatments like chemiclean either eliminate it from a system or suppresses it while it stays in the system. Cyano is not going to be anywhere in the tank there is not water, and a systemic treatment like chemiclean will go everywhere there is water, so why wouldn't chemiclean eliminate cyano from a system rather than only suppress it? If chemiclean kills any cyano in a reef tank, it should kill all the cyano in the reef tank provided it is used at the therapeutic level.

Another example of why chemiclean might not work in some situations is age of the product. IME, older chemiclean is not as effective as newer product. I buy new chemiclean whenever I treat, and any leftover is discarded if it is over 6 months from purchase. Learned this when I first started reefing using some old product and it did not kill the cyano.
 
Some tanks have crashed using chemiclean. It kills some of what's there but most experience a resurgence if underlying nutreint conditions aren't changed. Cyanobacteria is everywhere there is mositure and CO2 and light for most species , even in polar bear coats and lichen patches in otherwise dry areas . It is largely responsible for life on the planet as it fixes nitrogen,ie makes it bioabalaible and oxegenated the oceans. Provide food for it and it will come.

I agree 110%:thumbsup:

Cyanobacteria are virtually everywhere. It would not be surprising to find it on human skin, or dust particles that enter the aquarium. IMHO, it would not be realistic to believe we could keep a warm, wet, and brightly lit environment, like a reef tank, free from cyanobacteria. All we can hope for is that our husbandry keeps them from blooming.

For readers interested in knowing a little more abut the ubiquity ,nature and geological history of cyanobacteria this article may be of interest: nice pictures too:

Well, it's convenient but risky, I stopped using it many years ago. Don't need it anyway.

Die off and ammonia is one concern ,cyano giving off toxins is another. I have no idea what's in it and usually don't dump stuff in my tanks unless I know what it is .It may or may be selectively targeted to kill just cyano but I don't really know that.

As for new introductions,food is newly introduced. It likely has plenty of spores in the air too but I'll let you research that.

Here are just a few of the bad experiences posted by others:

There are many others .

Toxins released by cyano could certainly be another factor in a tank crash, but again, proper manual removal prior to treatment prevents this, followed by the recommended 20% WC post treatment. Toxin release facilitated by the product improperly administered by the user.

Food intro a definite possibility as well, probably dependent on how it is processed during packaging. I feed mainly Hikari frozen type foods (spirulina gut loaded brine and mysis), New Life Spectrum pellets, and Ocean Nutrition Formula I and II. I don't know if these products are irradiated or heated to a kill point for any possible cyano spores.
 
Cyano is not going to be anywhere in the tank there is not water,

Water is everywhere too even the air when it's close to 0 humidity. Few things are completely anhydrous; it's hard to keep them that way.
 
Many animals use cyano for food Spirulina is an example commonly used for enriching live and frozen foods.
 
I agree 110%:thumbsup:

Well, we live in climate controlled, air filtered environments, so so why would that not catch some, and who is to say that cyano in the air/on dust could survive in a marine environment? Can you say with any surety that a strain of fresh water cyano could live in salt water, or cyano on a bush outside our house could live in a salt water environment? I can't.

Is cyano, a primitive thing to start with, adaptable to the point that it can live on dust or skin, in an air dominant environment, then grow and thrive in a reef tank if it lands in there?

A salt water reef tank environment is pretty unique and different from anything else we have in our homes, and assuming that a dust borne, air dependent species of cyano that lands from the air in our tank is the same thing and has the same growth potential in a totally submerged, highly salt environment like a reef tank is erroneous at best.

Yes, but water is not everywhere at the same concentration. And what concentration will keep cyano alive? It sure grows well submerged in a reef tank, but do you see cyano growing in your home at 50% ambient humidity? I don't.
 
Do you know what spirulina is, btw?

I guess we've got the argument .No point in going further with it it.

There are plenty of chemiclean threads ; this one is about a cyano scrubber idea . I think it's been hijacked long enough,so take the last word if you must
but let me make sure I understand your points first:
. Here goes:
You can sterilize cyano bacteria out of your tank with chemiclean and you strongly advise others to use it . Chemiclean can be readily used without doing seen and unseen harm to other organisms in the tanks . It doesn't matter that we don't know what's in it and can't really asses what it might do. We know it kills cyano bacteria.

Further it sterilizes the tank so well that cyano wont come back for at least a year an then it only does so because you add something that has it.

Despite the fact that it is ubiquitous across the globe and food some enriched with with some variants of it is fed to the tank it won't shjow up in a tank previously sterilized with chemiclean. The fact that variants are ubiquitous and adapt to the harshest environs on the globe , even in minerals like calcium and lime makes no difference. It won't show up in a tank sterilized with chemiclean unless you put it back in with with new rock or something else .Even food loaded with it wont bring it back once chemiclean has done it's thing if the food is somehow sterilized .
The numerous folks who have had difficulty and have done harm to animals in their tanks with the chemiclean treatments can be dismissed since they are just not attentive or smart enough to follow directions carefully.

I totally disagree with all of that.

Recommend it all you want. Folks can use it if they wish . I think it's risky business and do not recommend it at all ,ever, anymore. Just too many failiures and unknowns. Ther ar much better ways to get rid of cyano bacteria with a little effort,imo.

Sure do, it is a species of green cyanobacteria. Not the Red Cyanobacteria we have been discussing. It is processed, heated, desiccated, and many times irradiated as it is manufactured into fish food. Have you ever had a green cyano outbreak after feeding spirulina or ever heard of one? I haven't.

So you are ending a hijack you have been an active participant in. Pot calls the kettle black there. I wasn't trying to have the last word, just civilly, not condescendingly, responding to yours and other posts on the chemiclean question I asked in this thread.

I posted my experience using chemiclean and state it is an option for those wanting to be rid of it. IME I have not had any tank issues that have crashed any system as long as the directions are followed exactly. Did I ever say no one else might not? No. I stated I have not.

Many folks successfully use Tech M to rid their tanks of bryopsis, and the active ingredient in that product that kills bryopsis is unknown to most. Unfortunately, in this hobby, anecdotal experience sometimes is what leads to solutions for issues instead of pure scientific research.

Unfortunately, your condescending summarization of my points tries to make it appear as if I am making a universal claim for how chemiclean works and will work for all users. I am not. I simply stated how it has worked for me in my own reef tanks.

tmz said:

I stated if I had to average how many times I have had a recurrence of red cyano in my tanks, is has been 1-2 years between outbreaks. And when I have had one it has followed a new fish or coral being placed into the tank. Again, my experience with the product, and not a statement for how it will exactly work for all users, albeit your biased summary attempts to make it sound as if I am saying that.

Red cyano has not come back in my tanks. Again, just posting my experience and not making any universal product claims as you would have it appear.


tmz said:

I have not experienced a recurrence feeding the foods I listed in a previous post. Did I state that any and all foods could not add red cyano spores that could cause it to redevelop? No. Just my experience with the foods I listed. No broad aquarium food industry covering statements here, just my experience.


tmz said:

Sorry, but do not put words in my mouth. I never stated users that had problems were not smart enough. That is your use of a derogatory description, not mine. The cases I have seen personally with any chemiclean issues have been user error, mainly not manually removing as much red cyano as possible prior to treatment. I cannot state that is the case with all issues, just the ones I have seen myself.

tmz said:

Which is perfectly within your rights, the same as it is for me to post my personal experience with a product.

That is the great thing about these Forums, readers have the ability to take what they wish, and leave the rest. There may be some failures/tank crashes related to chemiclean use that are not the result of user error. I cannot say yes or no to that, but that has not been my experience in my use of the product.
 
No condescension intended;just trying to understand your position and offer a caveat.

Chemiclean is risky and folks need to be careful with it if they choose to use it which I do not recommend at all.Many have had tank crashes or harm come form it including some very knowlegable ,careful reefers I know.
The ubiquitous nature of cyano bacteria is what it is. Reduce the conditions it thrives in ,detritus and nutrients, predominantly PO4 and it will wane. Provide food and adaptable conditions for it and it will appear.
 
Here are a couple of articles about marine cyano bacteria for readers interested in knowing a bit more about it. It's quite diverse and adaptable and a subject of much recent research seeking potentially beneficial undiscovered compounds which I found particulalry interesting.

It can also adapt it's pigmentation to greater advantage in the light source available. So, the color you see may not give you any clue as to the particular species you are viewing:
