Looking to purchase coconut carbon material and support gravel for a
residential style whole house filter. Not sure what type and quantity? How
can I tell how much filter media is needed to rebuild my existing filter
I use a carbon filter with a backwash valve on top, to keep my house water
clean. It has been in for some years and I know I need to change the
charcoal inside it.
I saw on your website that there are two different types of coconut shell
carbon. You showed something called "catalytic carbon", and it was more
expensive. Which is better?
