    DIY Filter

    After two recent requests to know more about my DIY filter I made for my paludarium, I have decided to post the details on here.

    Step 1

    Buy the following- one powerhead, a tall food box (mine was for pasta I think), enough tubing (I used the green eheim stuff), two plumbing 16mm connectors, and media of course.



    Push one tube (inlet) throught the connector on the bottom (this created a watertight seal) and one all the way through the top one. Then attach the end of the tube to the powerhead outlet. Fix the powerhead onto the inside of the lid; I used aquarium silicone. Fixing it onto the lid instead of the box means that the lid can be removed without disconnecting the tube. For the cable, I drilled a small hole in the side of the box, and wrapped a piece of rubber from a marigold glove around the cable before pushing it in. This sealed it.

    I then had a filter which looked like this:

    Ignore the duck tape on top, that was due to a split tube.

    The only problem is priming. I do this partly by syphoning (holding filter below water line and opening lid), and partly with a jug, filling up via the inlet tube.

    Wow, sounds good!

    Couldn't you make life simpler when it comes to cleaning by placing the powerhead at the bottom of the box and connecting the outlet to the bottom pipe? Then the water would be drawn from top to bottom, with the regularly cleaned floss being at the top, and the courser media being at the bottom.

    Thanks,
    Chris

    You could, but then the pump is pumping dirty water, with the result that it gets worn out faster.

    It wouldn't be pumping dirty water, not if it's at the bottom, beneath the media, with the outlet connected to the bottom pipe. Then, dirty water is sucked in through the top pipe, and cleaned in the media. It is then sucked into the pumps inlet, and blown out the outlet into the bottom pipe and then back into the tank.

    I might build this soon for Pablo's tank, I'm sure standard hose pipe line is both cheaper and just as effective as a tubing, and I think it's 16mm.

    Thanks,
    Chris

    You can get them from most food shops, make sure it has a proper seal on it though.

    Thanks,
    Chris

    I got mine from a local shop in Wells, Somerset called Whitings. Not a chain though. I'll try to check what the brand was tommorow for you. Yeah, it does have clips to hold the lid down which are really useful.

    Then your not looking in a posh enough kitchen shop! They're expensive, but very good. You might want to experiment, snap on lids might be good enough.

    Thanks,
    Chris

    I'm not sure air driven would create enough water current. A 600lph powerhead is £10.

    Also, where'd you get the sponges?
    By the look of it they're the over priced Juwel ones.

    Thanks,
    Chris

    They're normal bog standard ones- I buy the biggest un-branded ones my lfs has, and cut them to go in the juwel filters, hence they look like them. Except the anti-nitrate one, which I was trying as an experiment.

    I got my container from Matalan, it was only £3.50 and has a 2.2 liter capacity, and is air tight, which is important.
