    DIY Aquarium controller

    Anyone toying with a Raspberry Pi or an Arduino for automation? I currently have an Arduino Mega doing my calcium and alkalinity dosing as well as controlling my ATO that is directly plumbed into the RO/DI. Im currently adding pH monitoring, dual temp probe monitoring, and setting it up to control my refugium lighting. It will eventually do data logging, host a local website with stats, and will email when specific activities occur like after power resumes, if pH or temp are outside normal parameters. Hoping I will be able to also program in wavemaker control. At the moment, I only have 4 AC outlets relay controlled by the Arduino but I will eventually add at least 4 more. Once I get everything inside a case looking pretty I will post pics. Just wondering if anyone else is toying with these.

    Does it test your calk/alk?

    No. It dispenses the specified ml I enter in the programming at 2 different daily intervals I have specified. I still test it once a month to verify and make adjustments as needed.

    I thought about trying but just don't have the time or know-how to make it happen right now. It looks like you've got a great start!

    My system will basically be equivalent to an RKL with the cost coming in somewhere around 50$ for everything. Next step is getting a flow sensor working.

    That 50$ calculation does not include any of your probes does it?

    Depends... if I use an analog PH module (which work fine they just require mechanical calibration same as most PH meters),the price is like 8$ including the probe. The temp probes were a couple bucks, the arduino was 9$, the ethernet shield was like 7. Im thinking of upgrading to a digital module which allows for software calibration but that module still supports standard ph probes... Im not sold on the expensive pH probes and based on my testing I see no advantage especially when you consider you can get anywhere from 8-10 ph probes for the price of an expensive one.

    Well stated! I would be interested in seeing what you've got going on and if you're willing having you teach me a few things

    I am not a coder so I have been learning as I go but its not difficult. It just requires a lot of reading and truthfully, being good at math helps because there are a lot of similarities between math and coding. I am having a friend help me when it comes to coding the GUI since that is a little outside of my understanding. He codes for a living but so far I havent had to ask him for any help. At the moment, I need to connect to the arduino with a pc to change any of the dosing settings or set the clock which is not the best way of doing things. Once the GUI is done i will only need to connect to it to add new/updated code.
