Two types, doing different jobs — buy on what the water needs rather than replacing both at once.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eCoarse 4 Pack\u003c\/strong\u003e is the mechanical stage: it catches suspended waste and is the pad you rinse and eventually replace on a routine. The \u003cstrong\u003eFine Carbon \u0026amp; Zeolite 3 Pack\u003c\/strong\u003e polishes the water and pulls ammonia, which is useful in a new tank, after medicating, or in a small overstocked setup — but zeolite is exhausted rather than rinsed clean, so it is a consumable on a shorter cycle. Do not run carbon while dosing most medications.
