It's fun. I'm trying to rid my tank of a Cyano outbreak without using chemicals for the past couple weeks. My main concern with chemicals is killing off beneficial bacteria or anything else when using them. Additionally - I want to find the root of the issue and not use chemicals for a few days and have the Cyano return.
A little background - I am running a 210g mixed reef. It was officially launched about 3 years ago from my 75g but it has been moved several times. So - the 210 has been in its current place for almost 1 year which obviously causes some new tank syndrome from moving it (a bit of cycling). Recently I added a few fish and perhaps that threw the bioload off causing this outbreak since I was intentionally over feeding with the new fish.
My stats are below:
Salinity: 1.024
PH: 8.2
Mag: 1450
Alk: 10.9 dKH
Calcium: 480 ppm
Nitrate: 1 ppm
Phosphate: 0 ppm
Temp: 75
No ammonia
For the past two weeks I have been doing 15% water changes every few days while brushing the rocks off and sucking out the cyano during the water changes. I added an additional power head for more water movement as well. I seem to be managing the Cyano level but not reducing it. It comes back daily and it is irritating some corals. Any other ideas before I take the plunge in Cyano Rx or Chemiclean?
