I have not played with this yet but it is an interesting idea and should be fairly easy to accomplish.

In the link you posted they mention this pump at Adafruit. That appears that it would possibly work but they mention using a Peristaltic pump which would be my preference as well. They can be a bit more expensive like this one at Adafruit but you can find them a bit cheaper other places like this one on Amazon. With this type of pump you run less risk of the internals getting fouled since the liquid never comes in contact with any moving parts. In addition you can just weight one end of the tubing and drop it into your detergent bottle. No reservoirs or modifications required.

Next part is driving and controlling the motor. The common method is to use motor driver board containing an H-Bridge. A dual H-Bridge DC motor controller/stepper motor controller is what you will mostly find right now and can be pretty inexpensive. You can go the (sort of) easy route and get something like this shield for the Arduino but it is a little more expensive and has way more than you need for this project. Or just search on Amazon (or elsewhere)for "Dual H Bridge" and you will find many at well under half the price that will work perfectly fine for this. Some are even made for use with the Arduino.

As far has how to wire and program for this project, you will find plenty of tutorials and how-tos on Adafruit, YouTube, and many others.

I'll do a full write-up later as my design and parts keep changing. For now, I'm using a model B, a SainSmart 8-channel relay, a Pi Cobbler and these pumps. The pumps are powered individually with a 12v power supply.

I would automate:

  • water changes
  • water tests
  • chemical dosing (e.g. flourish excel, prime during water changes, flourish potassium etc etc).

    By having a cleanup crew (amano shrimp, nerite snails, siamese algae eaters) in my 75 I've managed to automate algae management and cleanliness.

    I've been thinking about the last one ... there are pumps you can buy on Amazon that do that like the Jebao Pump, and even considering DIY solutions like this with a Raspberry Pi.

I have the same one I think.
I'm pretty sure this is the same as the one I have
