DIY Bio Filter

thingiverse

This is a comprehensive DIY bio filter set printed in 3D. To complete this project, you'll need a Danner Mag drive pump with a capacity of 300-500 gallons per hour, PVC fittings, nuts and bolts, a trash can, gasket material, and high-quality filter media. It's highly recommended to use real filter media instead of shotgun wadding shown in the pictures. The majority of these printed parts are available for download separately; this set offers a convenient collection with accompanying images. The 3D printed parts include a 0.5 inch screen for the pump outflow, which will replace the PVC pipe with holes as seen inside the trashcan where the water from the pump flows through. This feature does not require any supports when printing properly oriented. Optional components included are a smaller two-part screen and a slip-to-thread adapter. You can use the two-part 4x4 1.5 inch screen for both drain and filter outflow instead of the small round one shown in the pictures as the drain screen. It's also advisable to apply silicone to the last elbow before it goes into the trash can. This will allow you to easily detach the pump if necessary, making repairs or replacements much simpler. This improved filter design places the pump outside the trashcan, significantly reducing maintenance complications that might arise from pump failures. With the magnetic-driven pumps being extremely efficient but requiring an initial burst of energy to get spinning, occasional tapping may be required to assist it in starting. Pump installation and connection is relatively straightforward, with all steps clearly illustrated in the accompanying images.
