Carbon in canister
EHEIM ECCO EASY 35 EXTERNAL CANISTER FILTER 2232
for my 10 G tank.
There is a Carbon Filter Pad, and based on the manual, it can be used only for about 10 days.
I thought Carbon Filter pad or bag should always be in a filter?
hob filter always has one, I had a fluval 305, it has 3 inside....kind of confusing...thanks
