Cyano

[Spooky_Whizz]

I don’t have corals. Just fish. Nitrate phosphate 0. I had cyano once before and I used chemiclean and phosguard and it went away quickly. After few months, it’s showing up again now. Chemiclean and phosguard don’t seem to be working much this time around. But I have been reading threads here and got more confused. In order to get rid of cyano, do I reduce or increase phosphate. Also, where does nitrate come into play in all this ? I am using RODI water and have been doing water changes every few days. Feeding normal twice a day. Light is on about 10-11 hours a day. More blackouts ?

I’d prefer natural ways to clean it instead of phosguard and chemiclean etc. don’t feel too comfortable.

How old is your tank ?

How old is your tank ?

6-7 months. First time I got cyano was right after I switched from freshwater to saltwater.

Cyano is part of a new tank stage

Did the tank improve? Diatoms are common in the early stages in a tank usually improve within a month or so, but cyano can be a continuous pain.

It’s still there. I have been using a couple of things to reduce phosphates. It has stopped spreading but rocks that were pink are not not clear yet. Good thing it’s not increasing in color intensity or area.

I have a very old mixed reef tank that cyno is impossible to keep out, even after treatment. While I do have plenty of flow, the cyno always returns 2 days after the treatment process is completed. I have a BB tank with alot of rock work. PO4 runs between .06 - .15ppm Nitrate between 0 -10ppm ( It grows in very high flow area's as well) I have it in 2 color versions (redish/purple and orange) I am also experiencing Dino's too. I use chemi-clean .
