Stop Water Changes During Cyano Outbreak?

[Addicted2Acro]

I have been sucking the cyano out almost daily and replacing the water. I heard someone say that you should not do water changes becuase cyano may like something in the new water. Assuming the RODI and everything is working as it should, is this true or should I continue to do water changes frequently?

I do not think that’s desirable. Cyano is, IMO, best dealt with by manual removal, higher glue, and reducing organic matter. Water changes help to export organics.

You need to cut your white light and increase flow to the sandbed also. Water change weekly with manual removal. Get cleaners that work the sand.

I’m not convinced on the white light since cyano uses blue just fine.

Agree but the white is also just adding more to the problem and if he has corals then he needs the blue and uv on with reduced duration.

Yeah I reduced whites and have been dosing a variety of bottled bacteria, KZ Cyano Clean, all with Coral Snow for the past couple days. Seems to be having a decent impact.

Have you tried @SunnyX method for coral snow and cyano removal? Check his thread. It works very well and easy to do.

Just a sec I have it saved someplace.

Basically you just make coral snow (Calcium Carbonate) as per usual and mix in bacteria of choice.

The theory is that the snow will take out the organic, and the bacteria will move into the new real estate.

Not sure on the scientific validity but it seems logical...

I've only felt with one outbreak. Granted it was a 3 month battle. I was vacuuming the sand bed and water changing weekly. I was blowing rocks and sand off and while polishing the water with filter socks. I did the previously mentioned SunnyX method. After about 2 months I stopped all these things and did 2 things. 1)added some live rock from a much more established system and 2) stopped water changing and disturbing the sand. My nutrients were really low though. Within a week I saw noticeable improvement. By the end of month 3 I had zero cyano anywhere in my tank whatsoever. Been like 5 months and still 100% cyano free. Idk whether it was the rock, the discontinued wc's, or if i just so happened to do those 2 things right as first 2 months of chasing my tail payed off. What I know, is I went from cyano covering everything and smothering corals to death, with as much flow as my corals could handle, to pristine, clean rocks and sand very rapidly.
