Just a bit of cyano...

[Ken]

Hi Kennyv, I had a client's aquarium many years ago with red tufa rock in it , the kind they sell at LFS for freshwater tanks and had an algae proble for many years that never seem to go away, despite many different ways to control it. I saw his tank, and saw that everything he did was right so I suggest he get rid of the red tufa rocks and put in live fiji rocks instead. A few months later his tank never had the algae back ever again. If you have only six inches of cyno, then I would simply siphon it out and follow the many good guideline of suggestions from our fellow aquarist. Regards Ken
