malawi_man Posted December 18, 2005 Report Share Posted December 18, 2005 Well here is how I made some DIY box filters. Start with a glass box - 7x8x12cm, glued together with silicone. Get a piece of stocking place carbon in it and tie it off at both ends, place this in the bottom of the glass box. Get a 14cm length of any type of plastic pipe and place a piece of airline down it so the airline just comes out the top. Place this in the box with the bottom in the middle of the carbon sack. Place filter wool all around the pipe to hold it in place. You have a box filter (or 5) How it works. Air passes through A and air bubbles come out at the bottom of the tube and pass up again through B. When the air bubbles go upwards they also bring water through with them. This creates a water flow where the water flows through C and D and then back up through B. I hope you understand. :roll: :bounce: Enjoy Quote Link to comment Share on other sites More sharing options...

Rory Posted December 18, 2005 Report Share Posted December 18, 2005 Very cool indeed! How many are you putting in you (what size) tank? And let us know how well they work ...Could you put another layer above the wool, of gravel to hold it all togeather? Quote Link to comment Share on other sites More sharing options...
malawi_man Posted December 19, 2005 Author Report Share Posted December 19, 2005 yes you could change it for any media, basically they are a diy version of some shops bought filters i have so they should be the same if not better, they are only going on 11 litre tanks but i have similar things on some 40litre tanks. maybe someone else knows more about what size tank.
