I imagine it writes its own code for adjusting the dosing right?

ok here are my questions.. 1st. do you think its worth the money and on that note how do you think it compares in versatility to the reefbot.. (which i understand you probably dont have 1st hand experience with) 2nd. its pretty awesome it controls dosers to steady things.. but if you weren't dosing and going the calcium reactor route, would it have any control in that aspect?

Tank Threads : 150 gallon Tank Automation with Reef-Pi

I do not calculate my time into the cost of building it. If I did that it would make the apex worth it. Another advantage to the apex is it seems to hold its value pretty well.

I enjoy the DIY aspect and I have a hard time swallowing how much an apex costs so it works out for me.

Now that I have a design down I think soldering / assembling the next one would be much quicker. There is only two boards that need soldered. The 12v splitout is very a very quick solder job. Maybe 10-20 minutes. The board that contains my power/ground header pins plus temperature sensor/waterlevel sensor hookup takes a good amount of time. My guess is I could take it out in a couple of hours.

For assembly, it probably took a couple hours to put all that in there and test it to make sure all my connections were correct.

Stringing the RO tubing through my walls took a while. Hooking up the RO tubing took an hour or so. In addition I had to fight cheap Chinese peristaltic pumps.

So lets start with a where are we now post. Here is a screen shot of my current Trident results.


Now let me explain some of the details of the shown graph. First the Alk graph looks like it is all over the place right? Well let me put some numbers to it to show how little it is actually changing. The high peak on the left side of the graph is 8.76dKh the last test at the right is 8.6dKh The low points throughout the graph are 8.56dKh so the represented range in that graph is 0.2dKh and that is over a 7 day period testing 4 times per day. The drop at the left is where I turned on the dosing control based on the Trident testing for my Alk and set the target number at 8.5dKh with a safety window of +- 0.3dKh. My Trident then started slowly reducing the dosing amount each day until the value is staying right around 8.5-8.6dKh consistently for the last 4.5 days. I plan on now using the dosing numbers that are logged to create a better dosing schedule that is closer to what the Trident controlled dosing is and that should tighten the swing up even more as the Trident will have to adjust my default dose less and less.
The Calcium graph is even more interesting. The peak just off the left side is 489ppm and the low dip just to the right is 469ppm. The bouncing up and down was the result of an empty new salt water container for my water change and my Trident trying to tune the new dosing amount to compensate. I then mixed new salt water and set a new target for the dosing and it flattened right out and has been 479-483ppm for the last three days.
Mag I am not dosing right now trying to get it to drop a little which you can see it is. The range on this graph is 1492ppm on the left to 1442ppm on the right. Target is 1420-1450ppm and then I will turn on dosing control to keep it there.
Questions on that part?

So have you guys watched any of the youtube videos or looked at the FAQ that Neptune has already put out? I'm just wondering where I should focus the write up.

I'll work on it there is a lot to put into it so it may get posted in sections. Is there one topic that you are most interested in? Maybe I could start with that.

Nice work. I too built a DIY controller years back. Mine was Arduino based and not Pi but had similar capabilities to what you are using yours for. After a while it just became too much to manage on top of maintaining my tanks so I bought an Apex.
Now I am doing things with Pi but it is connected to my 3D printer and not my aquarium.

Do you count your hourly rate for doing all of this work in building it, soldering, designing, printing, etc into the cost? About how many hours do you spend doing all of the soldering, wiring, assembly and such?

For those interested in information on the Trident the NDA that prevented me from talking about it much has now been lifted and I can talk about almost everything that I know about it now. So if you have questions about it please let me know. I will probably do a full write up here on it and what I know but it will be easier to answer individual questions in the mean time.

It has been extremely accurate but more important it has been extremely consistent. I can't tell you how accurate it is compared to other manual testing because I have no idea if the numbers that those test kits give is accurate in the first place and most of them are dependent on color change that every person see's differently. I can tell you that even as careful and as precise as I am at manually testing my results frequently had me testing a second or third time based on the results.
No the waste is dumped into a waste container or into a drain and not back into the tank. at only 15ml of water used for the complete set of tests it's not a lot of water going into the waste container. You also set the size of the waste container in Fusion and it tells you went it's getting full and needs to be emptied.

As a side note I buy most small items in multiples assuming I will use it again in another project. The prices I am listing is for the total, not the single item. Costs would go down if you were to buy with someone else and share.

RASPBERRY PI
-------
Pi Zero W - $14
32 GB SD Card - $6
12 vdc 3A Power Supply - $6

CONNECTORS
-----------
12v DC Power Supply Jack (10) - 6.95 (For plugging in power)
Stereo Audio male/female jack (10) - 5.99 (For Temperature sensors).
2 pin Wire Connectors (20) - 7.29
Aviation Plug Connector (10) - 10.90 (Used with the DF Robot Water level sensor. Its not needed, but I liked it better than using the DF Robot connector directly.
3 pin connector - $2.50 I used with the temperature sensor.

ELECTRICAL COMPONANTS
---------
L293D pump controller (5) - $6 For controlling Peristaltic Pumps
PCA9685 PWM board - $6 For controlling Peristaltic Pumps
DC to DC converter (5) - 10.75
DF Robot Water level sensor - $5.99 plus shipping
12VDC peristaltic pump - $25 ($7ish each) ($4 if your willing to wait for it to ship from china). Search EBAY. You want an inner tube diameter of 3 mm so that you can use drip irrigation connectors.
Temperature probe 6 foot (5) - $13 (These need coated in silicone. They will rust in salt water)

SOLDERING COMPONENTS
----------
4.7k resistors - $2 (Used with the temperature sensor)
1k resistors - $2 (Used with float switches, or water level sensors)
Female to Female Jumper wires - $2
StripBoard - $3 I like this for making my own boards
Header Pins - $2.50 Used in making my own boards
Terminal Block - $2.50 Makes it easy to disconnect / connect the 12v power to things.

MISC
-----------
Heat Shrink Tubing
Solder
Wire
Soldering Iron
Multi-meter

Taken with bulk it cost around $142. For only what you need exactly it would be around $100.

I have also bought stuff to control 8 outlets. That probably set me back another $30.
