Hi silver tang,

Wah whole day no answer?? Will try to answer what I had been using from the list on top... carbon.

Usually the change of carbon is around 8 weeks. But it largely depends on what brand and the amount of quantity being used. The manufacturer usually will give directions for it. Oh, and if you are using carbon, do remember to use one with the least amount of Phosphate as it will give algae bloom...dunt be like me..now scraping tank...lol

I using coral stones too, but haven't change it for the past 3/4 months. Anyone?

Actually, most of us do not use all of the above except carbon. Its because all these thing trap detritus and would cause nitrate problems in the future.
