Ah, yes! Chiumanfu's *excellent* Arduino-based monitoring system. I agree with most of his opinions, but his underlying concern (monitoring the system while on extended trips) is not applicable in my case, and makes most of his points moot. And for me, the benefits of using a RasPi far outweigh the Arduino's benefits. Yes, the Arduino is more reliable. But my Nagios monitoring system will let me know if my RasPi locks up or otherwise fails to respond -- Easy enough for me to walk outside and cycle the power on it.

Eventually I'm planning to start a new thread, focused entirely on my RasPi monitoring system. In fact, I may start that this weekend.

Jim,

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

JoelEB (a SparkFun user in Colorado) posted a great article there about six months ago:
https://www.sparkfun.com/news/1641
"Enginursday: Solving Real-World Problems with Data.SparkFun.com"
Using a RasPi and some DS18B20's (exactly what I'm wiring up!), created a temperature monitoring system at their makerspace. He's got some python code posted, looks similar to the adafruit DS18B20 tutorial, although quite a bit more capable! I'll use that as my starting point.

Hopefully when you have it all figured out you will make a build thread. And a code library that less computer savy people could use to built it. :thumbleft:

Of course! That's why we're all here, right? To help each other out!

Ammonia is still 0, and nitrites are dropping!

Unfortunately, nitrates are also dropping, and they weren't very high to begin with. I'll just keep feeding the fish, and hopefully the mosquitofish will start breeding to fill the tank.

If your beds were planted the plants may be taking all the nitrates your system can produce at the moment. Nothing to worry about.

Well, I have a few plants, but still plenty of room left in the GB. Earlier this evening, my wife was commenting that one of my pepper plants has already surpassed hers, and she planted almost a month before I did. So perhaps that *is* where all the nitrates are going...

I've been making an effort to feed my fish more often, and I think it's showing up in the water tests from today. Ammonia is not quite 0, nitrites are holding steady, and nitrates took a good jump! See the graph at:
http://open.sen.se/jrandomhacker/

I also finally remembered to take (and post!) a few pictures of my plants.

Here's the nitrification graph as of this evening:

I never did manage to get my ammonia above 0.1 ppm. Just not enough fish mass for the amount of water? I've only got about 20 mosquito fish, the largest of which might be 5 cm if he stretched his fins out. And a single goldfish, perhaps 7-8 cm? In a tank with about 750-800 L of water.

I'm hoping to get some redear sunfish in a month or so, when Freshwater Fish Co. is open to the public again:
http://freshwaterfishco.com/new-and-events/

How many should I be looking at getting?

I pulled out the Lennard calculator, plugged in 775 L for the FT. At 7 kg/m^3 with omnivorous fish, my single IBC GB should provide enough surface area for mineralization and nitrification. That works out to about 5.5 kg/12 pounds of sunfish, so I just need to figure out how much full-grown redears or blue gill weigh when grown out. IIRC, they're about 1-2 pounds each?

Red ears weigh more but the 1-2lbs average is spot on.

Thanks FF! So figure 1.5 lb per red ear, maybe 1 lb per blue gill?

That figure would be in your AP system. With a longer lifespan than most of us would let them live they can grow larger. One state has a fishing record of a 4+lb Bluegill. Here is a decent description from a fish farm in FL.

I'm getting ready to add some Maxi-Crop (Seasol) to my system, and I wanted to be sure I linked in the post below:
viewtopic.php?p=493990#p493990

15 mL/500 L of FT, every other week

I'm running about 750 L, but my plants need a pretty serious boost right now. So Ill be applying 15 mL per week until I see improvement. Hopefully when I get some larger fish (June 20, woot!), they'll help a bit too.
