cyano battle

[brisco]

Back from London, and the tank is looking good! No sign of Cyano yet, measured my Phos at zero and Nitrates at 5, so far so good.

I found it was definately water flow I moved my MP40s lower as I had cyano on the sandbed, once I did that it cleared up quickly, but then started higher on rock workj. moved MP40's backup and its all gone, even on sand. I also increased how powerful the mp40s were pumping during the day.

I do have chemclean onhand and have not used it in the last 3-4 months i have been experimenting with flow.

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.
