Hi I just want to share my experience in cyano
I used to fight cyano
previously for period of 2 months. After I start using distilled water then I noticed the cyano
is slowing going away. I also syphon it out weekly then I put in some Phosguard from Seachem into the filter.
Eventhough there is no trace of phosphate I was told cyano
exist because of phosphate therefore I use some Phosguard.
Eversince the cyano
has now gone so now I keep using this 2 things (distilled water and Phosguard).
Just some ideas.
