Nano Reactor 3D print

[chippwalters]

This small tank reactor is great for nano tanks under 40 gallons. It moves around 100 gallons an hour through the media bag.

I use it with pre-packaged bags of Chemipure Elite:

but you can use it with any media in a filter bag, including charcoal, gfo and other.

It requires the use of this inexpensive pump, which snaps directly into the side. You can get 2 of them for $18:

The unit can sit on the bottom of your sump or you can attach it to the wall using these 1.26 inch D x 1/8 inch neodymium disc magnets (always be careful when handling magnets!):

The magnets are enclosed in screw cap containers.

This reactor is super simple to operate and clean. You can easily snap the pump on and off the unit, and there are no holes on the bottom so it won't drip water when your remove it from your sump. Just unscrew the lid to swap out the media bag.

I printed it in PLA using a .4mm nozzle with .2mm layer height. Printed on my MK3S+

Brilliant design @chippwalters! It’s really well thought out.

 

Do you worry about the magnets inside the tank corroding over time? Encasing them in silicone before assembly might be the easiest solution.

I'm doing some testing, keeping both magnets inside the tank, with one side dry and the other wet and we'll see. As you know, GFO is mostly rust, so I'm not too worried. A professional aquarium  management company is now trying the reactor out with steel wool to see how well it can help manage water chemistry.
