That's pretty slick, but the easiest/cheapest filter is no filter at all. On a well established tank with a decent biodiversity and lots of plants there really is no need for a filter, other than for circulation. A small powerhead is often enough to keep things moving without having any real filtration.

A small HOB is only $20, looks better and you can put plants in the box.

That looks like a good idea, but I'd have a few concerns.

1. Cleaning - does the gunk all fall out the bottom when you remove that thing from the tank to clean it?

2. Appearance - You'd need to hide that thing pretty well so it doesn't look like you're going for the "polluted river" look, complete with authentic discarded soda bottle.

3. Efficiency - Is that powerhead really strong enough to pull water through all of that media?

4. Design - Will the media fall out the bottom of the bottle once laded with goop? Will the bottle fall off of the powerhead due to the "press fit" connection not being tight enough?

I agree with evilhorde, if you want a cheap filter, just stick with a HOB. Marineland Penguin HOB filters are very cheap and do a great job. They look better in the tank, are easy to clean/maintain, have parts readily available, can add carbon when needed for post medication treatment, the reasons just go on and on. For the price of a decent powerhead you can get a good HOB. If you just have a powerhead laying around and are looking for something to mess around with, than maybe it would work for you, but the mass produced models made by Marineland, Aquaclear, etc would probably do a better job at filtration in the long run.

Here is a link to a Penguin 100 from bigalspets.com. For a little over $10 you have a good filter, that is designed for tanks 10-15 gallons. Hard to get a better value of quality product for low price......

^^ That's a great filter, I run a pair of them in one of my 20H's. Yank the filter cartridge out, fill it with matrix, and put a sponge filter on the intake. Awesome setup.

This is a good idea if you have an extra powerhead and you want extra filtration.

I am all for DIY but sometimes it's just better to spend the money. After you buy all the PVC, the can, the pump and the hose and then factor in the time spent, I suspect you could have bought a new HOB.

I also tend to do things the long way. I don't like seeing pumps or airlines or any equipment if I can help it.

In this tank (which has since been torn down) all the filtration is done in tank underground. The pump is accessable (sort of) and the only equipment visible is an airline and a power cord hidden behind some rocks. The new 50 gallon tank mentioned in the thread is up and running and if I get motivated I will sort through the pictures and make a new thread for it but for now the original unimproved model will do.
