Hi guys and gals
It's been about 3 months, so should I replace my charcoal (carbon) cartridge ?
I have a 15 gallon tank.
I have a Pann Plax 400 cascade internal filter with bio foam and then a carbon ( charcoal ).
On the leaflet it talks about replacing monthly, but someone told me it's every 3 months.
Questions:
1) When must I replace?
2) any advise when doing it?
3) will water parameters be influenced?
Thank you all!!!
