how often should i change rowaphos in fr?

I think it depends on ur PO4 reading. If the PO4 keeps rising fr a low reading, it should be changed.

Can estimate about 4-6weeks la... But as your po4 gets lower the media also last longer... Like what bro above said, testing is ur best friend... For me, when i need to clean my glass more often i change.... Haha

Ideally monthly but also depend on your bio load. If bio load and nutriant is high you might need to change more often.

Best is still testing. Based on test, u can roughly know when to change provided no change in bioload.
