Generally, how long can Phosban be used?

Depends on how much phosphate your tank has. I left mine too long the first time (over a month b4 the first change), and once I changed it, noticed a big difference. I would change it after the first couple of weeks, and then see how things go. It definitely worked well for eliminating the hair algae…..Hope that helps!

After the initial dose it usually last a couple of months at least. As Jason points out, phosphate testing is the main way to determine when you need to renew it.
