What happens if I fill a canister with granular carbon but than after installation very little water flows through? How do I resolve this? Thanks!
There are several variables that may cause that. Typically a granular filter like yours is only good for 5 GPM or so.
I have several of these canisters and they're great, but eventually the foam pads wear out. How can I replace those?
We do not sell the foam pads because the canisters are so cheap to replace, just replace the canister.
When you fill a refillable filter do you need a funnel or a scoop? When you fill the refillable filter do you just fill the canister completely?For most canisters we use a funnel and fill them full of media. We usually fill them, shake them and top them off. Then install the sponge ends and tighten them. If you are looking at a GreenWave cartridge, it is only partially filled.
How much filter media does it take to fill the canister?
Each canister will hold about .15 cu/ft of media.
