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)
Pipe $ 1.98
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.
...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.
