My battle with Cyano and what I am doing to beat it....

[JimD]

I was just discussing the importance of sandbed maintenance with another member yesterday. It can only process X ammount of gunk before it turns into a sink and begins releasing back into the water causing all kinds of problems. Before I went bare bottom, I let mine go for over five years without anything and I paid for it dearly. If I ever go back to a DSB I would change out at least a quarter of the sand every year or so just to keep it fresh. I wouldnt recommend what Scorpino did unless youre very confident in your abilities and have the time to constantly monitor your perameters. Glad your tank is coming around Erik. When my sandbed crashed, I was this close to shutting it down, glad I didnt.
