Yes, my thoughts exactly JB. My only quibble is the "bell-less" term, because really what you're getting rid of is the media guard. (And good riddance, IMO!)

I added a single goldfish today, hoping that will be enough to keep my bacteria colonies at least a little active for the next 10 days or so.

My solitary goldfish got some new friends today--A woman from Sac/Yolo Vector Control dropped off about 20 mosquitofish for the FT this morning.

I've been testing the water almost daily since I got my system running about two weeks ago. So far the data is only logged in a journal. I've been looking at options for recording and graphing it, ("data visualization", to use the buzzword du jour), but I haven't found anything I'm completely satisfied with yet. I may end up just sticking it in Excel and generating graphs manually for the time being. (I did, and it was a pain in the butt, as expected.)

I've seen little-to-no ammonia, and my pH seems to be stuck at 8.2, but the nitrites and nitrates are starting to come up. A graph would look pretty awesome right about now...
Image
Ammonia is the red line, scaled by *100 in this graph.
Nitrite is the green line, scaled by *10 for this.
And nitrate (unscaled) is the blue line.

Most of my plants have some decent-looking new growth on them. I took some photos this evening, and I'll post them tomorrow.

Hey JimV, good to see that your system is cycling. It shouldn't be too long before the nitrite starts to come down too. What fish are you planning to grow, after you have you mosquitofish toastie triangle hors d'oeuvres?

I'm not sure yet, but I think I'll start with red eared sunfish (a close relative of the bluegill).

The project I'm working on right now is setting up a temperature monitor on the FT. I'd like to see what the temperature extremes are over a whole year, so I know what sort of fish would be suitable. What I would *really* like to raise is rainbow trout, if I can keep the FT cool enough.

Looking at you temperature stats, its not very different to here where we can grow rainbow trout seasonally over autumn-winter-spring.

Your summer is a bit hotter, more like inland Victoria away from the moderating influence of the ocean.
My temperature probes arrived last week. Just waiting on my tech savvy OH to build and install the raspberry pi monitoring system.

Yep, summer is definitely the problem. Also, I haven't found a source of rainbow trout yet, although I haven't done a thorough search.

I'm also using a Raspberry Pi for my monitoring system. What sort of thermal sensor(s) did you get? I'm using some inexpensive "1-Wire" sensors, which I enclosed in PTFE (Teflon) shrink tube. I'll post pictures of my setup, assuming I have some more time to finish it this weekend. It's still on my workbench, hooked up on a breadboard. So I've got some soldering and weather-proofing to do still.

Jim, I've noticed I can steer the water temps up or down depending on how/when I flow water through vertical fence post towers filled with gravel. Even during summer, I'm thinking I can pull the temp down several degrees by only circulating at night. Something to think about.

Thanks, Nate! I'll keep that in mind. No towers yet, but something to consider for the future.

I've been trying out some data logging and visualization services. The visualization software that I'm happiest with so far is Open.Sen.se

My public page there http://open.sen.se/jrandomhacker/ currently has a graph of nitrogen-related data, but I can't seem to embed it here because it uses raw html.

Jim,

If you have the room a section of NFTs, will also work. Plus you can pump to a smaller head height saving power.

Okay, just tossing some things out here, for lack of a better place to put them (and time to find such):

https://www.sparkfun.com/news/1808 talks about Tour de Tanks and the author's monitoring systems.

https://data.sparkfun.com (which I think I posted earlier?) is SparkFun's service for uploading "IoT" data.

They also posted an entry https://www.sparkfun.com/news/1814 about 10 days ago, discussing several other IoT sites.

Jim,

Also look at this thread here. Towards the end he mentions why he chose not to use the raspberry Pi.

Thanks, FF! I'll keep that in mind. Out of curiosity, how much room do NFT's take up?

Not a true NFT, but most backyarders use a standard 3in pvc pipe. Cut it as short as you want. Bend it around corners. Build an A frame and run them up both sides. Basically it depends on you.
