I've had my substrate in my tank for years now. Never changed it but have added small portions at a time due to syphoning during water changes.
I've read on another forum of a guy that changes 20% of his sand every 6 to 8 weeks as a way of reducing phosphate. He uses dry sand as phosphate is minimal to non exisant in it.
On saying this, I didnt know I was supposed to replace my substrate. How often am I supposed to change my sand and how much at a time? Take in mind I have approximately 100 lbs of rock in the tank.
