antwan Posted September 25, 2006 Report Share Posted September 25, 2006 sure will Quote Link to comment Share on other sites More sharing options...
malawi_man Posted September 25, 2006 Report Share Posted September 25, 2006 umm, there will be alot of air build up in the bottom so flow wont be very good. You could seal off the bottom and put the air line with air stone down a tube in the middle, the water will flow through the media and then the air bubbles will bring with water back out the pipe.

alanmin4304 Posted September 25, 2006 Report Share Posted September 25, 2006 It wont work as drawn but as stated, using the airstone in a tube can carry the water from the bottom and create a drop in water pressure so the tank water runs through the filter will work.

SilverBlade86 Posted September 25, 2006 Author Report Share Posted September 25, 2006 So this would work just fine? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted September 25, 2006 Report Share Posted September 25, 2006 Have a look at the stem on an undergravel filter or a box fiter. Each has a tube with air bubbles rising up it. It is the water that is rising between the bubbles that makes it work not the bubbles themselves. You need a tube to carry a rising column of water not air bubbles to make it work. The air bubbles are a way of removing some of the water from the bottom of the filter so the tank water flows through the filter to replace it (and is filtered as it does) Quote Link to comment Share on other sites More sharing options...
Nana Luke Posted July 6, 2008 Report Share Posted July 6, 2008 Just to bump this thread up a few years. I'm looking at building one of these myself, and found it easier to understand a diagram rather than photos of a build process I've been looking at. So I've edited the pictures according your posted specs - note the air stone is inside a tube. Is either of these correct? or does the bottom end need to be completely sealed up, so no holes are drilled. Should the tube with the air stone inside be sealed either end? and my main question, WILL IT WORK? HALP. Quote Link to comment Share on other sites More sharing options...
suphew Posted July 6, 2008 Report Share Posted July 6, 2008 The first Pic would work but has a lot of un-nessary bits, the second wont work. All you need is the tube and the sponge, if you put holes in the side of the tube where it is in the sponge it will suck water more evenly through the sponge. The longer you make the tube the better it will draw (suck) the water. Pic two would work if you didn't have the holes in the bottom. The air stone doesn't need to be a tight fit in the tube as shown Quote Link to comment Share on other sites More sharing options...
Nana Luke Posted July 6, 2008 Report Share Posted July 6, 2008 Ok I think I understand you. I just need the tube that the air stone is in and the sponge on the outside of that?? No outter tube? none of this filter wool stuff? Your help is much appreciated Quote Link to comment Share on other sites More sharing options...

cichlid7 Posted July 6, 2008 Report Share Posted July 6, 2008 I made 15 of these for my killie tanks they work very well i made them from glass they are 5cm x 5cm x 12cm tall i drilled lots of little holes at the bottom 4cm of a 13cm long 20mm pvc pipe then put that in the glass box then put stone/gravel in up to 5cm, then filled it up with filter wool stuck and airstone down to the bottom of the pvc pipe put it in the tank turned the air pump on and away it went. i could see things that were floating around in the tanks being sucked down onto the filter wool. It does a great job IMO see diagram HTH Quote Link to comment Share on other sites More sharing options...
Nana Luke Posted July 7, 2008 Report Share Posted July 7, 2008 That looks like a bloody good idea and it looks pretty easy to implement! Will try that out - might just modify it a little bit so i don't have to find a glass box that size! Thanks a bunch for your help! Quote Link to comment Share on other sites More sharing options...
cichlid7 Posted July 7, 2008 Report Share Posted July 7, 2008 hey i built the glass box myself But i also used old fish food containers they also worked great Quote Link to comment Share on other sites More sharing options...
Nana Luke Posted July 7, 2008 Report Share Posted July 7, 2008 Just rummaged through mums cupboard and found a nice square glass vase that is near perfect to those dimensions. just not quite as tall. haha let's hope she doesn't notice that it's gone :lol: Quote Link to comment Share on other sites More sharing options...
