Coffee filters????

Coffee filters for what?

Personally I'm not much of a fan of drip coffee, I prefer espresso . . . I've been rockin' the Italian-style stovetop espresso maker for a few years now.

With regards to using coffee filters in your tank somehow, don't they get all soggy and fall apart after they've been wet for awhile?
 
I don't know how long they last. If they don't last long that may be why they aren't used.
 
Try it out, theres nothing bad about the composition of coffee filters (I'll be surprised if it holds up to any kind of pressure other than a drip, but) . . . let us know how it goes. Are you already using another type of filter that you're wanting to replace?
 
They are not porous enough to allow free flow through them. You would have to force the water through them. In that type of setup they would clog very easily and rip due to the pressure.

Stick with filter socks.
 
I'm not thinking of 1 but several in series to lighten the load of one. I might try it. It seems that no one has tried this yet, perhaps.
 
why not just use a micron filter in a canister? Servers the same purpose, and most of them can be cleaned and reused several times.
 
The reason nobody has "tried" iti because the filters are not porous enough to allow free flow through them. Like I said, you would need to force the water through. They will clog very quickly AND rip due to the pressure needed to get the required flow through them.

Filter socks are cheap and perfect for what you are trying to do. As mentioned a power filter is also suitable.
 
It's not about money and I already have a working filter system, I use poly filter from walmart and lots of it.

It's more a principle thing, can it be done? Will it work? would there be any chemical things that would be bad?

If it did work, it would be really cool. Might be an alternative for other aquarists. It's outside the overpriced aquarium retail box.
 
No, it will not work. Again, the filters are not porous enough to allow the water through at a reasonable rate. That means you will have to FORCE the water through them. The pores are so small that the filter will quickly clog anyway. This will reduce the flow further and increase the pressure needed to move the water.

Without a HUGE surface area to allow the water to pass, the filters will clog quickly and/or tear due to the pressure.

I don't know how to explain it in more basic terms.

Open the lid of your coffee pot and time how long it takes to pour 1 gallon of water through the filter.

Now take that filter and hold it over your powerhead and see how quickly it fails.


Nice idea, but it is just not something that is going to work.
