Details
In our 3 gallon fish tank, the flow from our AquaClear 20 water filter can be a bit intense. Even on the lower settings, it creates a crater in the substrate and generates a slight water flow that affects the plants in the entire tank. This would also have an affect on any fish inside the tank.
To mitigate this, we designed a cute baffle that would diffuse the force of the water as it falls from the water filter. Even with the filter at max power, with this mounted in the way, there is no more substrate cratering or pushing around of plants.
Our next step is to design an additional baffle (perhaps in the shape of a dock) to reduce surface water disruption, for our floating plants.
Printing
We printed in PLA. I did a test of PETG and it also worked. (However, I did not have wood colored PETG, so we kept the PLA print in our tank)
I enabled supports for both prints, from the build plate only.
I kept the water wheel at a lower infill, and set the base to 100% infill. This way there would be a bit more flexibility in the arms for getting the wheel to the necessary slot. The wheel I kept at a lighter infill in order to help it spin easier.
Assembly
In order to assemble this, you will need suction cups. We used two (2) 30mm suction cups. Just push them through the mounting holes.
There are four sets of water wheel holes - you can place the water wheel into whichever set you like. You may need to adjust which hole to use, based on the intensity of your water flow through the filter. The speed of the wheel may vary, depending on where you mount it, and the intensity of your water flow.
Note: The water wheel is slightly smaller than the width of the base - this is intentional, so that it's able to more easily spin freely. In earlier tests, if the arms holding the wheel were touching the sides, it inhibited free movement.
We preferred placing the water wheel half above / half below the waterline. Partly because of aesthetics but also because it appeared to diffuse the water best in this location.
If your wheel is not spinning:
- Check that one side of the water wheel is not pressed up / rubbing against the mounting arm
- Try adjusting which set of holes the wheel is mounted in
- Check the side of the wheel that sat towards the print bed; you may need to slightly file down the initial layer of material on that side's peg.
- Add more water to the tank
