I am hoping someone can help as i am new to tropical fish. I have 2 tanks, one with gravel & one with sand. The tank with sand has 4 ruby barbs and 4 corys, but what i need to know is how to clean the sand or do i need to replace it and if so how often?

Here's an old thread on sand that may help.

Thanks for link, found it intersting and helpful.
