screwdababylon - First nice cabinet you got there just saw you thread for the first time. I would not recommend building your own carbon filter. Obviously smell is important and i feel spending a little bit of money here would be warranted. I have tried my own twice and have had not had success. I will always buy them from now on.
I cant speak to those filters you linked to. But if it were me i would maybe consider a proven manufacturer.
If you do build your own, dont use carbon from the pet-store, order some good stuff. Make sure you pack the carbon tight by vibrating the filter when adding the carbon.
Best of luck...
Oh and i don't know of a formula but if you had a formula the quality or adsobtion of the carbon would an included variable. I bet carbon from the fish store is 5 times less effective than carbon used by canfilter for example.
yeah i know its important and i would go and buy one if i lived in US
but i dont have any of those here and all the local growers use self made carbon filters
thats some kind of a challenge for me))) like wtf! if thay can do i can do it too!
those sellers i mentioned do ship to my country
and others dont - thats the problem
if anyone can recomend me a store based in europe that would be cool!!!!!
becouse shipping of the cfilter and carbon across the ocean is a bit expensive
THE AQUARIUM CARBON IS DIFFERENT FROM THE ONE USED IN GOOD FILTERS
but this difference is not so dramatic as u say
even the dude who sell the filters told me that
he said that this difference will reduce its life lenght but not the odor filtration
thanks for the tips mate!
but i will continue attempts to make one)
