Backyard Aquaponics
A place to discuss aquaponics

An invite to the Dark Side, really Ron.

Good eyes Ron.

Toes reviled!!!

I'll add that to my list of mysteries, unless it's just that the rain, and car tires that tend to carry the hole away.

But that is a good question.

Where do holes go?

In the last place we lived (in the country), we were lucky enough to live next door to a (no-cat-tail specialist) 40+ cat owning cat woman.

She was on the local council.

The result was I got to see the difference 'tween roads that were instantly maintained when a pothole started to do it's thing, and the roads that she didn't drive on.

In one decent rain event, the drip from the leaves off a tree could dig a hole through asphalt. Literally within 24 hours. Once the hole is started, I think car tires take over.

I believe it was Archimedes that said, "Give me a Gum tree and some rain, and I can drill through the earth"... Or something along those lines

Once when I was ...perhaps.. seven, I was in Madang and was playing next to a 5 foot high dirt wall. I saw a handful of dirt collapse to the ground spontaneously.

I was an oddly ... awareingnessly, thought provoking, ...witnessing.

Sometimes stuff just falls down because it's been up for long enough apparently.

It was only a little bit of dirt, but I had a funny feeling is was important, and forever. That dirt was never going to go back.

Perhaps potholes have always preferred to be somewhere else.

This is why I tend to do lots of small posts rather than just dumping my brain in one big hit. I think I'm going to stop trying to limit the number of posts by saying more than one off topic thing per post.

I dont think it works.

I've been away on a fishing holiday.

Today I bought a new tent.



See.

Did ya catch a big fish??

It was hard to get them to show without climbing up into the grow bed where the light was. Here's a shot that was overexposed; it's lousy of everything else, but it shows the toes.

Oh, THAT'S who said that.

It's funny how, despite one of his most famous stories involves him jumping out of the bath and running naked down the street shouting, "Eureka!" we take all the stuff he said so seriously. Nowadays if a person does that, about the only job he can hope to get afterward is in politics, and he'll never be taken seriously again.

I had a teacher in high school who had a baby during the school year, and named it Eureka. I used to daydream in class about her losing her child in Wal-Mart and running through the aisles screaming, "Eureka! Eureka!"

If it had been a boy, she was going to name it Kirby. I guess she had a thing for vacuum cleaners.


That should be recorded in the annals of...wherever it is people record quotes for future generations to recite when they want to be profound.


I was getting worried. You really should not post about things like your incredibly dangerous home-made jigsaw just before vanishing for days.

Although I was thinking that if you had managed just to mangle yourself without dying, they might give you a wound vac in the hospital, and I wondered what sort of inventions it might inspire you to think of. Wound vacs are at least as interesting as nebulizers.

I retract the said statement, nice toes

It is a strange fetish this forum has....

I work in psych, so I feel right at home here.

Okay, actual aquaponics question:

Last night (actually night before last, since it's after midnight here, but in my mind it's not tomorrow until I've slept) when I first put water in my system, the air temp was 48ᵒF and the water temp was 53ᵒF. (Sorry, no F to C conversions tonight; I don't have enough brain cells left.)

This morning (actually yesterday morning, but I still haven't slept, so...) before work I went out to check on things. The air temp was 56ᵒF and the water temp was 58ᵒF.

I can understand the morning air temp being 8 degrees warmer than the night air temp, since the sun was up and things were warming up. But I do not understand how the water got warmer, especially since it was 5 whole degrees warmer, not to mention being warmer than the current air temp.

I honestly thought my thermometer was malfunctioning. I stuck it in the other sump tank, which has some standing water in it but hasn't been connected to the system yet, and that water was significantly colder (I've forgotten how much; I want to say it was 47ᵒF, but I'm not sure). That didn't seem possible, so I stuck my fingers in both batches of water, and the standing water was, indeed, MUCH colder. (EDIT: Both of the sump tanks are buried to the same depth, about 12", so the ground temp isn't influencing the difference.)

Could it be the moving water is warmer due to friction from all the pumping and squeezing through pipes and splashing and stuff? Part of my brain says that makes perfect sense, and the other part says if that were so, then I should be able to make it splash around a bunch more and use it to heat the greenhouse. And then both parts scoff at each other, which tells me I should probably stop piddling around on the boards and go to sleep.

Good night!

Perhaps the water you filled the tank with.... was warmer in the pipes.... and is now cooling toward air temps in the tank...

The friction of stirring water does indeed make it warmer, but only by the amount a really cool lab might detect.

I'm guessing you finger is less sensitive.

So I'm going to go out on a limb here, and without reservation say "There's something else going on".

Bam!

That's commitment!

I'm struggling to hold even those four figures in my gin and tonic, but might they simply reflect a lag that water experiences after a bit of night time warmth?

ie 4am saw an increase in ambient temperature for 3 hours even though the sun was over here.

Nope.

Nope.

And nope.

On the night of Dec 3, I dragged the hose out to the greenhouse to put water in my system. After filling the working part, I didn't want to be bothered with walking all the way back up to the house to turn the hose off just yet, so I stuck it over in the as-yet-unconnected sump tank to let it run in there while I did other stuff, and went and turned it off a while later, so that tank is about half full now, with water that came from the same place, at the same time and temperature.

All the water came from our well, so all of it came in at ground temperature, 53ᵒ. The two sump tanks are about 3 feet apart, both buried about a foot in the dirt. The only difference is that in one, the water is just sitting there, and in the other, it's circulating.

The air temp when I put the water in was 48ᵒ and falling, as the sun had gone down. I'm not sure what the low was that night, but it would have been somewhere in the high 30s. It poured rain all night, so I seriously doubt there could have been any sort of temperature increase. When I went out in the morning (I didn't have to be at work until noon, so it was well into morning, around 10:30), the sun was up and warming the greenhouse, so the temp was rising back up, and had made it to 56ᵒ. The circulating water was 58ᵒ, and the standing water was forty-somethingᵒ -- that was by the thermometer; I only stuck my fingers in because I didn't believe it, but the difference was very obvious, so then I had to believe it.

This is weird. I need to know why it is.

I guess I should drag my butt out of bed and go record today's temperatures before getting ready for work. (I got home 3 hours later than I was supposed to, due to a surplus of psych issues among the current batch of patients, so I'm having a hard time waking up...)

I think my thermometer has a way to record highs and lows, too, but I haven't figured out how to see them.

My hubs has brought me coffee in bed. Ahhhhhhh.
