Hi,
Just received my free sample today and thought I would post up my findings on here.
I have a 300litre sumped tank and over the last few months I have been battling with what I thought was Cyano. I dosed regularly with Zeobak and Coral snow with no effect so I switched to Cyanoclean and Coral snow, still no effect.
About a month ago after more research I came across on a thread about Dinoflagettes? so I decided to do a 3 day blackout. This worked to begin with, I could see all the red disapearing from the sand and the rocks and also the bubbles had all gone. However over the last few weeks I’ve gradually been getting a build up of what looks like green Cyano?
I’m going to start dosing tomorrow and will update this post as and when.
