Mature tank, no chemicals, how did YOU beat Cyano?

[beesnreefs]

If you defeated Cyano in a mature mixed reef WITHOUT USING CHEMICALS (like Chemiclean), I’d like to hear from you! By “mature” I mean a system running successfully for at least two years

What did you do to win the battle? (Details please!)

How long did it take?

Did the Cyano stay away?

Did other issues (dinos, GHA, etc) pop up after?

I recommend to reduce white light intensity or even turn them off for 3-5 days. Add liquid bacteria daily for a week during the day at 1.5ml per 10 gallons. Add Hydrogen peroxide at night at 1ml per 10 gallons. Add a pouch of chemipure Elite which will balance phos and nitrate and keep them in check. peroxide is an oxidizer and not chemical

After the 5 days, add a few snails such as cerith, margarita, astrea and nassarius plus 6-8 blue leg hermits to take control.
Inadequate water flow is often a chief cause of cyano blooms as slow moving water combined with excessive dissolved nutrients creates red slime algae development

Dose carbon while making sure that your phosphate and nitrate are away from zero. A real sand sifting gobby will turn the sand. Increase the flow and keep blowing the cyano away

Are you saying they should carbon dose? That can easily fuel cyano.

Just to be clear, while I appreciate the generalized advice, that’s not the purpose of this thread.

I’m looking for real-world examples from people who had Cyano in a mature tank and defeated it without chemical (eg, Chemiclean) intervention

DIY coral snow with ZEOBAC worked for me.
I'm sure any other good bacterial additive would work.

Ok no chemicals how about pharmaceuticals? Cipro will kill it dead. I was using it for Euphyllia issues, but it killed a few patches of red cyano (likely from carbon dosing) dead. Cipro works well by itself and never tried any of the concoctions with chemiclean, cipro and other stuff. Cipro is pretty controversial in the aquarium world, but many shops run it full time in LPS tanks especially with Euphyllia. Plus, it's a lifesaver if you have a fortune invested in Euphyllia and have an outbreak of brown jelly disease.

Can you expand a bit on what you did?

Sorry should have been clearer. I meant no pharmaceuticals. Curious how people beat Cyano without antibiotics

I've not had severe cyano fortunately at any stage but occasionally it creeps in.
I use calcium carbonate at around 1/4 teaspoon with 20ml tank water & two drops of zeobak.
Shake up well, draw into a Syringe & shoot in front of a wave maker.
I do this 2-3 times a week without the bac as a simple flocculant & add bac if any little patches of cyano show up.it quickly deals with it

Ammonia dosing.

I had patches of dinos pop up when my nitrates bottomed out so I started ammonia dosing. The dinos were quickly covered by cyano and then the cyano disappeared shortly after.

I nitrate dose using calcium nitrate and it hasn’t affected Cyano sadly. Maybe the ammonia helps nitrifying bacteria out compete Cyano.

I’ve used the hydrogen peroxide + less white light gameplay in a mature reef but these days my tank is too happy to risk messing with those things when the cyano appears. I can vouch for that combo working, though.

Old fashioned way then... toothbrush, turkey baster or powerhead. Unless your tank is covered in it that actually works quite well with some patience. If you use ozone or UV it should kill anything in the water stream that's not filtered out by a sock.

Yes, but together with the rest of my "recipe" other bacteria will take over (IME). In near-zero nitrate and phosphate cyano specifically has the advantage.

I quote myself "IME". I now have a hair-algae problem, but that's a different, unrelated issue.

A UV unit killed mine, but I had the easy dinos (ostreopsis).

I introduced cyano by reducing powerhead power and creation areas of weak current. I intentionally lowered current to acclimate new things. And unintentionally got some cyano patches.

Increasing flow back to normal didn’t help. But I know it keeps it away.

I did use chemiclean because I’ve had good results with it before. And it did get rid of the cyano.

With my pumps back to normal speed it hasn’t returned.

Regardless how you choose to treat it, I would say a possible reason you got it would be too low of flow in those areas
