cyano battle

I did increase my flow as well, so perhaps that is part of the solution. I too have some chemi-clean on hand....so perhaps this threat is helping too!

Well I was away for another week and came back to a small patch of the dreaded cyano! It was on the sand bed in an area of lower flow so I have vacummed it it and performed a 25% water change, changed the filter socks too. I will try to change the flow in the tank to hit up that spot some more. Let's hope that helps.

Hi,

How often do you change your filter socks. I was told by J&L to change them every 3 days. It takes 3 days to create nitrates in the socks.

I had good results with ChemiClean as well. I followed the directions very,very carefully but I had to turn off the skimmer for a week even with water changes. In the long run, prevention is better: reduce nitrates and phosphates, increase water flow.
