Cyano all over my sandbed, noticed my nitrates are very very low.

[Randy Holmes-Farley]

Thanks Randy

yep, I was asking the later, why would it be useful against cyano if low nitrates isn’t the problem in the first place. Thanks for clarifying.

Even if it is low, I don't think it useful in this context, but certainly if nitrate is not low, it's hard to imagine utility to boosting it higher.

I don't agree that the Redfield ratio is of any value in this context, or really most any context in reefing.

I also do not believe that raising nutrients is known to help reduce cyano. How could that actually happen?

How that can possibly happen, such as with dinos, is rather complicated. Nutrients cannot ever deter growth of an organisms like any of these. I do not believe there is any evidence in the scientific literature of raising nutrients directly deterring the growth of a photosynthetic organism.

What it can do is perhaps spur the growth of something else that outcompetes them for something else, like a trace element (likely with dinos, but this has not been demonstrated with cyano that I have ever seen).

Hi Randy .Cant say anything further cause you are one expert that I follow myself .
However, Read all Topics on Cyano and found " 0 " Solution anywhere in them. (less Cyano Rx). Talked to Seniors like Mike Pelleta but it was like keep cleaning.. etc
Having said that, trying above Solved my Cyano for Good. Still if i bring Po4 towards .03 and it starts coming back in sump at one spot and As i elevate PO4 it stars going weak and dying. Cant Comment Why and How. But Would Love to hear something on Cyano from you in manner simple reefrs can understand. Regards

First, I must compliment you on a very diplomatic response!

A question I always ask people who have solved their cyanobacteria infestation, why do you have to keep re-applying the solution?

The advocates of increasing nitrate when cyanobacteria begins to grow continually need to deal with the next flare up In the system. And when they build a new system, they have to deal with cyanobacteria flare ups. What type of cure is that? I am glad they don’t have a patent or we would be spending a bunch of money for another “miracle” cure in a bottle. So why are we so convinced that tweaks to nutrient levels control microorganisms in aquaria?

The typical report on dealing with nuisance microorganism growth might be summed up as: see a flare up, “do something“, flare up subsides. The problem with such anecdotal data is that information is missing, for example, the more likely situation was: see a flair, “do something”, flare up does not subside, “do something” again + adjust X, flare up subsides. And yet, the second episode is reported to fit the popular narrative “do something” was the cure. No one applying the nutrient adjustment for cyanobacteria control is just doing nutrient adjustments, i.e., no one is running controlled experiments.

I am definitely NOT calling aquarists liars and conspiracy advocates. I am pointing out that it is very difficult to determine cause and effect relationships in uncontrolled experiments.

My usual recommendation for cyano is to manually remove, increase flow, reduce organics (skimming, GAC, Purigen, etc.), keep nitrate and phosphate at reasonable levels. Stop organic carbon dosing, if it seems to correlate

Chemiclean is a solution for you?

 

[Randy Holmes-Farley]

Chemiclean is a solution for you?

Not sure who you are aiming this to as the cyano problem that started this thread was six years ago, but yes, antibiotics such as Chemiclean can be used to deal with bad cyanoproblems.

 

[GARRIGA]

Yet to find scientific evidence that the type of cyano we see is detrimental and fact it consumes nutrients then perhaps can be controlled in such a way as to assist naturally with that function. Easy enough to manually remove yet impossible to eradicate. Removal a form of export and it's always likely present. Free turf like scrubber.

Am I wrong?

After chemiclean treatment, is sure that we "open the door" at Dyno or other or it's a only legend?

You free up real estate for something to grow in. I don’t claim that killing cyano with antibiotics is going to cause dinos.

I'm try to balance No3 and Po4 in this moment.. Maybe I've to much Po4... If it doesn't work I've buy Rx cyano..

OK, let us know what happens.

How’d things turn out?
