    During the process of setting up my 5ft tank I was looking around for a new skimmer.
    Needless to say I was a little shocked to see the amount of money I needed to shell out.

    So I undertook to build my own. After some research and inspiration of ToppDoggs DIY Skimmer. I set off to the hardware to collect the parts.

    The first attempt saw me attach an inlet pipe of 20mm and outlet of 20mm, First big mistake. The skim cup overflowed immediately using a 2000l/h pump. First Lesson Learned. Then I had to re-drill a larger hole around that fitting. Not easy but I managed.

    Next once that was complete I got my OPT-2000 and with the 32mm outlet, connected it up and off we went This time the bubble level reached only 3/4 the way up the cylinder.
    So I had to cut off 60mm off the top down (to 340mm from 400mm) and redo the neck again.

    Finally its done, not the neatest job but with a little planning, and the use on my new Dremel, we can get the joins a little neater using PVC weld. Here are the pics.

    OK, Pads, stop holding out on us, where did you get that pipe?????.... the cost of perspex tubing is the biggest cost excl the pump

    Nice Work Pads - How are you controlling the water level in the skimmer body?
    Now we have to see it in action!

    Yeah tell me bout it, I went to Plastic world and they quoted like R700 or 800 per meter. Ouch!!! So I went to Maizeys and got PVC, like R350 odd per meter. So I've got a 400mm and 100mm piece waiting to be made into another one.

    For sure. I put it into a bucket with some DT water to see about the water level. It seems that the water level in the chamber is ratio of the pressure on the outlet(thus most have valves) and the height of the water that surrounds the outside the chamber.

    Also the taller the outlet pipe the greater the pressure then the higher the water level in the chamber. But a higher pressure effects the performance of the pump and venturi thus limiting the amount of bubbles. A little more complicated than initially expected.


    I've personally done a DIY control type cap valve which you turn horizontally to limit flow to increase the water height.


    Dude so am I. My little JEBO has done me proud, believe it or not, but its days are numbered. I'll post pic of the skimmer in action soon.

    Hey Les, you forgot PVC :whistling: I find it easy to work with as most of the plumbing fitting are PVC so you only need one sealant for both. But if you welding then that's another case all together.
