But it doesn't stay chemical for long if you forget about it.\u003c\/p\u003e\n\u003cp\u003eLike filter floss, \u003cstrong\u003ebacteria eventually move in and it turns into a biological filter\u003c\/strong\u003e. Same trap: the day you finally change it, you throw out the bacterial colony that relocated into it — and your tank takes an ammonia spike.\u003c\/p\u003e\n\u003cp\u003eExcept carbon has a nastier side. \u003cstrong\u003eAs it ages and reaches saturation, it releases what it had absorbed.\u003c\/strong\u003e Everything it patiently pulled out of your water goes right back in. Old carbon isn't neutral: it works against you.\u003c\/p\u003e\n\u003cp\u003eThat's why the pack has 4 pouches. One pouch, one week.
