Building a Nano canister filter.

I thought this was the best idea I'd heard all year.

So I decided to go for it.

you can see the lead up to this thread here

So as it stands, this filter must contain all of the powerhead, heater and filtration internally to leave the nano free from crap that I don't want to see.

The price for all of this is as follows (remember these prices are in AUD)

Jar $3.00
Powerhead $10.00
Pipe $ 1.98
Grommets $3.00
silicon $6.50
So at the moment, the additional cost would be in the order of $24.50

I chose a 1.25L glass jar with stainless steel lid and plastic thread.

I wanted to fit all of this into it.


you can see a 25w heater and a small Poseidon filter, it's not great but it's good enough for our purposes, you can see I've found a whole bunch of grommets to allow everything to pass through the lid.

I wandered off to the shed and attacked the lid with a drill press and a dremel to come out with a useable lid.



Here it is with everything but the heater fitted.


So after fitting everything, it's time to test.

IT WORKS!!

...but not perfectly.



Even with silicon added to all the grommets they just weren't up to the pressure of around 1m head. So back to the drawing board.

I've found some nice electrical bulkhead connections which should take care of the leaks, and they're cheap $1.25!!!

More on that later.

This is one DIY project where I think it is not worth your time. Why? It's not easy to get this to stop leaking, and the thought that it will start to spray water while you are vacationing on the other side of the continent is just... worth the additional $20 or what for a commercial, proven unit.

I have been looking into building a DIY canister filter using a water filter cartridge, but they are not cheap, while some canister filters are... so there you go.

Let us know how it works out with the bulkheads.

Well you can't get a good curare down.

A few hours in the workshop and this time It's a definite useable SEALED unit.

Okay, here's the unit in it's "test bed" read the laundry sink, as having things explode anywaywhere else was just too much of a pain...


It worked at this height, but I wanted to test it at the maximum allowable head to see if the additional pressure would cause it to weep.
So the "ghetto" testing rig was expanded to include a test tank as high as possible, also note the magical elixir that makes my projects possible, and the cleanup towel should things go a little awry.


By JOVE!



I left it running for 4 hours solidly to check everything, and no leaks.
Even at maximum extension (and the pump is working hard, I'm still getting 240L/hr, so I figure that's pretty damn good, if not a little too good for a tank of this size.

No the biggest hole is for the purple thing, i.e. the heater, that's incorporated into the canister too.

The smallest is for the power cord, and the other two are for inlet / outlet

Here's an Idea.... Make a Nano Filter out of that beer bottle. Magical elixir ROCKS!

Beautifully done DIY! Any plans for a large one? Maybe an extra hole for a UV sterlizer.

Some details on bending acrylic lilly pipes

To be honest, there's no reason why you couldn't go for a larger one, but I think the time spent and just getting things to work, a point would be reached where a commercial unit would be more econmomical.

Doesn't mean that I won't try it.

This is a MKI version and there are some things in this unit that if I did it again I'd do differently. But we'll see what the MK II looks like

Well here it is pumping away quite happily now attached to the tank it will be married to for the next while.



On closer inspection of the cannister, you can see that half is set up as a "swirl pot" for the heater, and the other half is set up as the filter unit. These are divided by a peice of PET clear plastic that goes the full width of the cannister and down to about 9/10 of the length.


it works pretty effectively as the white floss is now terracotta coloured from removing suspended solids out of the water column.

Congratulations. You just bumped up an almost 15 month old thread.

As for the heater, you will always need to take risks. I tried a simple one myself, it kept the water pretty good temps, but when there is a leak, you drain part of the tank, destroy or damage your heater, etc.

A Lexan bottle might work for this type of thing, might allow for more hole drilling options as well.
