| so the direct answer is not much. it depends how much carbon, how often you change it, water flow rate/volume. i wouldn't put too much faith into in, you'd need an aweful lot of activated carbon at trickle rates for it to work well. i may be mistaken, but probably not very many people on this board use a gadget like that. you might want to do a forum search for trickle water changes.
remember the reason activated carbon works is I think the pores absorb material. once they're full... game over. if you don't get enough contact time, well, stuff passes thru -- and i don't think it has AI to pick what good stuff to let thru, and what to capture.
like the smallish amount of carbon, that would fit at the end of a hose, might be effective at trickle rates for 300 gallons. just a wild guess, could be even less. |
