I've been researching GFO today and can't seem to get an answer about how long it usually lasts... From what I've read it's a combo of "when I see algae" and around 2ish months as the norm... I know it's dependent on a lot of different things such as bioload, feeding, tank volume etc...
Just wondering if people could chime in when they replace it and about how big their tank is... Thanks!:.
