I had some cyano in my tank recently. I ran some GFO and scraped some of it off and ran lights out for about 3 days and it helped significantly. I have also noticed that it only grows in areas with low flow so if a specific area is problematic you could try increasing the flow. But my tank is also young so your results may vary. Hopefully someone with an established tank can offer advice.

just had a bad case of cyano myself and i did a big water change(between 30-40 gallons on a 120 gallon tank) every week for 3 weeks and after that it seemed to go away. i haven't seen it since and its been about 4 weeks. I would try a couple of bigger water changes maybe do 20 - 30 gallon in one change.
HTH good luck

I dont think it can be your salt, at least I have never heard of it being salt before. The reason all of your test are coming back low is because you are feeding the algea. You have phos in you system its just that the algea eats it and it wont show up on your tests. I had a big problem with it as well. I did lights out method and it would work ... for a few weeks then it would come right back. you need to find what is putting the phos into the system and solve that problem. Lights out is just a short term solution for a long term problem.

Check your RO system with a new meter to make sure you are really getting 0PPM. Your meter could have gone bad after 5 1/2 years.

Keep doing large water changes and exporting the algea. also flow is very usefull in fighting it.

chemiclean the tank and/or take your rock out and let it sit in the dark for a month.

I had a bad case as well.. However, my tank is only about 6 months old.. But, I bought a Foxface one spot, and he ate it all up.. Was really surprised to see him to go after it.

This is the method I used. Be anal about water changes. Do lights out every 3 weeks till it's all gone. It won't happen overnight. Mine took three months. I don't recommend chemclean. While it will kill the cyano, it will kill beneficial bacteria also.
