Got a few questions.

1) It's just any old sponge right providing it hasn't been used for anything else

2)Would it be possible to use any container. For instance a properly cleaned small drinks bottle with top cut off.

3) Is there a limit to how much air you can you through I have a very large airpump.

Thanks

1) It MUST NOT BE CELLULOSE otherwise it will rot and you will have big problems. Make sure it is clean.
2) Of course.
3) There is no physical limit that I know of. Mor air might need a bigger tube.

If anybody else wants help with this in the future, email me: seivadmas@@@gmail...com.

Replace '@@@' with '@' and '...' with '.'

Many thanks .

Also, you could stick a powerhead on instead of an air pump.

Thanks,

What's an airpump and life tube? Also, how much do these cost?

okay, I dont have an aquarium yet so i dont know all the mumbo jumbo technical talk, so i naturally have some questions:

In your 4th picture (where the tubing is coming out of the filter), is that tubing that will eventually hold the airline?

In your 5th and 6th picture you say to drill a hole in the tubing, In the pic it looks like the hole is on the very edge of the tubing, can i just put the airline through the the top of the tubing, instead of making a hole?

How long should all the different tubings be?

Would there be too much of a current for bettas to deal with?

What goes on the inside of the tank, and what goes on the outside?

The tubing with the airline in it connects to the airpump, right? Then do you put the end with the airstone in the filter?

What could you use to drill the hole in the tubing? A knife?

In your last picture that huge tubing isnt sticking out, I'm confused!

How does this filter intake water?

Thanks! I think I understand it but I want to make sure.

This is going to be for a 5 gallon divided tank for 2 betta

Edit- So you just put the tube into the can, fill it 3/4 gravel and 1/4 sponge, then stick the airline through the tube? and connect the airline to the airpump?

i tried to make one and i think it working....? the one i made air bubbles goes out the intake pipe. it that suppose to happen or through the filter medium.??

the pipe that goes up does the top of this go above or below the waterline, i like it though

could i use multiple of these for a 10 gallon? also how mcuh does an air pump cost?

mine cost £7 so im shure you could get a small one for around $10

I hate to burst the bubble here, but Lees has been making corner/box filters for decades. Their smallest costs $2.19 or so and ones good for a 100 gal tank run about $6.50. You can use any media you want in them.

Holy Crap! A box filter for a 100 gallon!!! I thought they were only meant for small tanks like 10 gallons

can you post pictures of every wngle of the finished product, im a bit sceptic

Thanks for the idea Sammydee

My 5min filter works like a charm!

ahh below the water line then ill set to work on it now

Yeah you want it below the water line so that gravity doesnt reduce the flow out of the top of the "outpipe". It still works when the top is out of the water, water is forced out of the tube but in the form of bubbles. Therefore keep it below the water line and the flow will be greater.

just one question i have:
are there any holes in the bottom of the fish food pot or do you just leave the bottom...well, holeless?

There are no holes in the bottom of the pot, you want the air bubbles travelling up the plastic tube to cause a suction that will pull the water down through the gravel and filter material. If you put holes in the bottom of the pot tub it would prevent this from happening.

Sorry sammydee, I dont mean to be hijacking your post.

can you use a coffie filter instead of a sponge?
