2011/05/21 - Once more into the breach, dear friends

My dad drove out today and we picked up another batch of fish from the fishery.  My dad hadn't seen the place before, and the owner gave us a nice tour.  My dad was just as impressed as I am.  What an amazing place.

So the owner sold me about 50 fish (plus a few because he's a nice guy) and I've just now gotten them into their new home.  I can't show pictures of them, unfortunately.  The bin I transported them was lined in black plastic, so you couldn't see them.  And now they're all in my huge tank, happily hiding in the deep water.  But they're between 2" and 3".  Some black some gold.  And all destined to be dinner some day.  :-)

Meanwhile here's an update on the plants:

Chard is still out of control.  I was going to harvest extra and make ravioli filing, and veggie chips, but I just haven't had time.  Perhaps tomorrow evening.  Meanwhile my ex in laws are coming out tomorrow and I'll send them home with as much as they'll take.


The tomatoes I transplanted to the new beds are recovering from their shock.  In fact, I have one tomato ripening to a beautiful red!  The plants in the old bed are as healthy as anyone could possible ask.

The cilantro got much too leggy.  I suspect it was from being in the shade of the monster tomato plants.

The strawberries continue to produce... and I continue to eat them the moment they're ripe enough.  LOL.  I have yet to get one out of the greenhouse.

The armenian cucumber is growing up its stake.  The seedlings (brussels sprouts, leeks, radishes, carrots, arugula, savoy cabbage, red romaine, green bibb, beets... did I miss anyone?) are all recovering from their water deprivation during the construction.  Overall, everyone is happy and healthy.

If I have time (I know: famous last words) this weekend I'll be building a simple moving bed bio filter.  I plan to put it in the rear sump, so the barrel-beds have that aeration to themselves.  It would be best for the overall health of the system if I put it directly in the fishtank, or between the fishtank and the growbeds, but with the configuration the way it is I think this is the right way to go for now.  This is the one I plan to build:

2011/05/07 - RIP sweet fishies

No pictures on this one.

Saturday morning I went out to feed the fish.  They were lively and it was a pleasure to hang out with them.  I did my water tests and the pH was still just a tad higher than I wanted it to be, so I splashed some acid into the sump tank.  Evidently it was too much.  Three hours later I had floaters.  I started flushing with tap water, but my mother was there to celebrate Mother's Day, and she's not an AP fanatic.  So putting her off wasn't an option.  When I came home from dinner I flushed some more water through.  By morning the remainder were floating.  I spent Sunday replacing 90% of the water.

I'm pretty upset about it.

2011/05/01 - A LOT of work done!

Over the last 2 weeks I've been expanding.  I built half-barrel growbeds on wooden frames (a la Travis Hughey) and am attaching them to the main setup.  Okay, let's be more accurate: I've cut two barrels, built one frame, and cut a lot of parts to make more... later.

But meanwhile, I got one set completely built and hooked up.  And I've transfered 4 tomato plants into it.  And finally separated all the new little seedings into their own homes in the big bed (now that there's room).

For the new barrel-beds, I've gone to what will eventually be a sub-surface constant-flow system.  I've got a drain hole about 3" from the base, and I'm planning to run the water constantly so it just stays 3" full at all times.  Since I'm using clay media, the wicking action will provide all the necessary water and nutrients to the plants.  That's the theory anyway, as explained by one of the Aquaponics gurus I trust.  But I admit I'm nervous about this one.

I haven't converted the main bed yet.  So it will fill up to 8" before overflowing.  Because of that, I'm still running the 15 on / 45 off timer.  Also, since I (don't ask) installed drain piping smaller than I intended, I am not confident enough that the barrels won't flood.  Plus I haven't glued all of the PVC or properly tested for leaks yet.  So, to keep from accidentally losing enough water to run my pump dry, I'm sticking with the 15/45 for a while.

And honestly I'm wondering whether I should convert the big bed, or just run a small secondary pump from the sump into the new constant-flow beds.  One of the advantages would be that most of the solids are removed by the second sump.  The direct fishtank overflow, on the other hand, is at its dirtiest.  And Gary, the AP guru, strongly recommends removing solids.  Particularly in a constant flow system.  The main bed currently has a large filter pad between it and the fishtank, so the solids are being handled there (if crudely).  But the new beds don't have that built in.  If I feed those from the second sump, it solves that problem.  And I'm sure there are still more than enough nutrients in that water.  That's not a concern to me at all.

Another option (and probably a better one long term) is to run the overflow into some type of filter before returning it to its current path.  But honestly I can't face doing that right now.  I've got enough construction projects.  So I think for now I'll run it on its own pump.  That also ensures that the main bed continues to get the high volume of water it's used to.

Plus the second sump is where I planned to pull for my vertical towers when I put them in.  For those I definitely want to have the solids removed.  While the clay beds can handle it if they need to (though imperfectly) the towers really shouldn't.

And now for the pictures!

All seedlings ready to transplant:

And a week later - more than ready:

Tomatoes (I didn't hand polinate - obviously something got into the greenhouse and took care of it):

Swish chard darkening nicely.  I've been eating some and it's delicious:


Overgrown lettuce before being thrown to the fish:

Yesterday's 2 being after 24 hours as fish snack:


Okay, now on to the new barrel-beds!

I cut the barrels in half using my jig saw.  It was a lot easier than I'd feared:

I purchased a chop saw at my local pawn shop.  I prefer not to use most power tools, as I'm a very small girl without a lot of muscle, and I don't like to use anything that dangerous unless I feel I can properly control it.  But the chop saw is completely stable and self-contained.  I'm really comfortable using it. 

 As evidenced by the mountain of lumber I plowed through

Here's the top of a frame, upside down while I attach the cross supports:

 And here it is right side up:

 And with the legs and barrel halves:

With all the additional cutting done (with help from my friend and her boyfriend on Saturday) I should be able to put another set together relatively easily.  Plus I've done all the complicated plumbing work, I just need to extend it to plug in new sets as I build them.

Though I do need to change the barrel outflow to a larger diameter pipe.  Sigh.  Next weekend.  :-)
