Chuckmeister Posted July 13, 2015 Share Posted July 13, 2015 These filters are incredibly easy to make, very cheap and work very well. (It’s also fun eating and drinking the contents of the items requiredItems you will need are:1a. An empty 4 lt ice cream container1b. An empty 2 lt ice cream container1c. An empty 500 gm round margarine containerThe options above are dependant on the size tank you want to filter and further on, you will also notice different size soft drink bottles needed to complement the above. The following pictures were taken of the 4lt container.You will also need:2a and b. The neck of a 1.25lt or 2lt soft drink bottle2c. The neck of a 600ml soft drink bottle3. Two lengths of airline (total length to reach from the bottom of your tank to your air supply)4. One adjustable air valve5. Coral rubble, shellgrit, coral sand or any media of your choice keeping in mind that this filtration will also help buffer the water and will need to be cleaned/washed on a regular basis eg every 2-4 weeks. Filter wool is not recommended although filter matting can be used as a top layer.6. An airstone (plastic candy striped ones are better than pumice - try Atlantis for some. They are invincible.)Preparation and assembly instructions:1. You need to punch as many small holes into the lid of the container as possible. One larger hole needs to be placed into a corner for your airline and a larger hole needs to go into the centre of the lid to be able to accommodate/suit the neck of your soft drink bottle.2. You also need to cut your drink bottle (keep the neck end and throw away the rest) at a height/length that will sit snugly in your container and suit the lid height also. The lid should eventually sit at the bottom of the thread on the neck of the bottle as this will keep it held in place. Punch two or three rows of small holes into the base of your drink bottle and again, a larger hole closer to the neck to accommodate the airline. If you are finding it difficult to punch these holes, you can cut V’s into the edge with a pair of scissors getting a \/\/\/\/\/ effect which also works well. You can now feed your airline through the hole and add your airstone.3. Place your drink bottle top into the centre of your container making sure the airline sits facing a corner. You can now add the media of your choice up to the base of the bottle neck.4. Feed your airline through the corner hole in the lid and push the lid into place on your container. Locate the filter in your tank and then add your air valve (just above the lid is good) and reconnect to your air supply.5. Sit back and relaxRemember, these are only a lightweight filter and are not designed for over populated or heavily fed tanks. Basically, they are a glorified corner filter at a fraction of the costThis post has been promoted to an article Link to comment Share on other sites More sharing options...

Ged Posted July 14, 2015 Share Posted July 14, 2015 Another great design and so easy. Thanks for the DIY lesson. Would the addition of an airlift tube increase the water flow through the filter? Link to comment Share on other sites More sharing options...
E4G13M4N Posted July 16, 2015 Share Posted July 16, 2015 Used to do something similar years ago, no lids just a piece of under gravel plate or those round godlfish bowl style onesthen cover with gravel worked a treat.. Link to comment Share on other sites More sharing options...
Ducksta Posted July 16, 2015 Share Posted July 16, 2015 These filters are beasts. Way underestimated.I operated plenty of tanks (mainly just raising fry) on nothing but gravel filled ice cream buckets.I eventually upgraded to sponge filters - purely because they are easier to move around and keep loaded up in another tank while a tank is shut down.

When I had a fish room every tank had one of these. Breeding tanks cause i had excess air and fry tanks because they are so good at it.Downside is they are not pretty but you get that on larger scale I guess.
