DIY - Nano canister filter


With the impossibility of finding a small canister filter on the market, I decided to make one by myself in DIY version.
All needed parts are from Ebay and cost me about $25 total. Most expencive part was Eheim throttle valve which is needed for flow reduction. 
Needed parts:



For filter chasing i have used Lock&Lock 350ml storage container. Very solid build and thick wall:



First step - drilling:



This is 12mm to 9mm 1/4BSP thread air pneumatic elbow quick fitting:


Same for the lid:


I have used  DC12V 3m 240L/H ultra quiet brushless motor submersible pump:

 
It is attached to the lid by 10x10 M4 DD type rubber anti vibration mount:




To keep filter material above the intake i have used guard metal mesh for PC computer fan 60mm diameter  AVOID this part, it is not stainless steel - it rust!!! It is better to use some coarse filter material such as ceramic rings as a bottom layer.



Finished product:


I am running this filter on my 1 gallon nano. With reduced flow to 1/3 it doing great job:

  3. For drilling the holes in the container you need 12mm borer.

  4. Hi, Have you used some kind of resin or glue for fixing the elbows to container?

    ReplyDelete
  5. Hello, I have used only Thread seal tape. The elbow is fixed by its thread.

  6. hey thanks for quick reply!
    Do you mean white teflon tape? I also see you have used some kind of black washer in between. I have ordered most of the parts. Thanks for the idea!!

  7. Yes, teflon tape. There is rubber ring, but it is not needed.

  8. Ok great!
    So is this filter still in use? Looks quite efficient, a miniature eheim classic...

  9. Did you silicone the mounts to the lid?

    ReplyDelete
  10. No silicone, it is universal glue. Silicone is not good for gluing plastic.

    1. Hi, I have used 12mm to 9mm 1/4bsp elbow: https://www.ebay.com/p/1444365762?iid=291564198341
      On the pump outlet you should put piece of 9/12 hose and then it fits perfectly.

  16. Thanks a lot! Bolbi, yesterday i bought the elbows!

  17. This is brilliant! The only think I would try is to fine a way to use a smaller hose. Do you think the lid would leak with more powerful pump?

    1. Hi, I don't know. This was made as small canister filter and this pump is to strong for my needs. I wish I could find smaller one.
