OK so now this thread has made me decide that I need to convert at least one of my beds to Flood/drain so I can stick asparagus, rhubarb, grapes and garlic in the AP... assuming they all need to be in flood/drain or they won't grow well being wet all the time.

I should make my wife read through your threads, seeing all of the different beds chocked full of goodness makes me want to expand outside of the greenhouse (but she's not keen on the idea). I built raised dirt beds in the garden this year, I should have just bit the bullet and made them AP beds! I have started debating about a second greenhouse, just a polytunnel that I could put in the part of the garden that I didn't build the raised dirt beds in, so maybe I can make that half of the garden AP and leave the other half raised dirt beds that I just built this year.

The AP is certainly vastly more productive than our dirt beds were, and uses only about 1/10 the water.

We are going to see if we can grow some potatoes in bags shortly, sitting on top of a GB or WB so just the bottom
gets wet.

Fairly steady water temperature over recent weeks, with the fish eating a bit less when the water is colder, but not very hungry when it is below about 8C.

I found a 24cm dead trout this afternoon, no apparent reason for it, the first in quite a long time. The dog enjoyed a fresh fish dinner.

Lots of peas just about ready to pick now, and getting heaps of rhubarb and parsley lately. Garlic, onions and brassicas growing well.

Ongoing warm weather is keeping the water at a reasonable temp for this time of year and the trout eating well. There are a couple of really big ones in there now, carry-overs from last year. I'm feeding them 800-1000g of pellets per day, and adding 100g of KOH most days, interspersed with 300g of dolomite every few days.
I measured NO3 on the 11th Aug, and it was about 60ppm. On the 17th I measured pH6.48 and salinity 958ppm, and added 3.5kg of salt. I'm going to add a lot more today to bring it up nearer to 2ppt, as the fin rot hasn't gone yet, even with a few weeks of UV steriliser use.

I cleaned out the blue drum filter after about 2 weeks, but I'll need to do that every week or so from now on as feeding increases.

I've nearly finished setting up a housing for the 2 Hailea air pumps, 24VDC>240VAC inverter, and a charger, plus going to dig a hole for a plastic tub to hold 2 X 150AH 12V batteries.
One air pump will run off the house circuits, and the other from the batteries via the inverter, both running continuously. I'll install a couple of solar panels for battery charging soon too.

When feeding the trout some breakfast and adding 100g of KOH this morning, I had a look down into the tank near the circulation pump, only to discover one of last year's batch of trout had died, and was caught in the temperature probe cable. by the look of it I suspected it was chock full of eggs, and indeed that was the case! About 300g of caviar, which I'm sure the dog will enjoy.

49cm long trout

Looking rather deflated after squeezing out the eggs

It was a bit stiff, but that happens pretty quickly after death at 10C, however, the eyes were nice and clear, and it didn't smell, so I cooked it on the BBQ. I've only eaten about a quarter of it so far, but it was nice- the flavour was a bit more subtle than most we've eaten lately- not sure if that is due to its size, or it having been dead a while.

I can see there are others in the tank of similar size.

Here is the now well shaded FT, and garden surround, the FT will be covered in Pandorea pandorana 'Ruby Bells" (a variety of Wonga Wonga vine) flowers in a few days, along with the orange flowering succulents which are starting as well.

Looks like life is returning to your part of the world Gordon. A grim outlook for us up here, but I guess we have to play fair. I am looking forward to what this year brings for you southerners and what new AP items show up on the forum seems how you guys are so far ahead of us for AP.

I moved my asparagus to a wicking bed after the first season. They are very invasive and have HUGE root systems.

An Aluminium box, as often found on the back of utes, turned on its end to make an essentially waterproof enclosure. We've added screened vents at the top on both sides, and at the centre bottom, to allow the heat to escape, and I'll be adding a 24VDC fan above the bottom vent, controlled by a 35C thermostat, to improve cooling in hot weather. I aim to have the box shaded before it gets too hot, but the maple tree will provide some additional shading, and a vine over a wire arch out of view on the right also provides afternoon shade.
Shelving is open to allow air circulation

From the top:
24VDC->240VAC 350W inverter
5 outlet powerboard, with white WEMO switch clearly visible
240VAC->24VDC power supply for water circulation pump (hard to see at the back) +
Hailea V-60 air pump + enclosure for DC connections
24V battery charger + Hailea V-60 air pump
Attachment:
Air-pumps-etc.jpg
Air-pumps-etc.jpg [ 381.9 KiB | Viewed 1483 times ]



One V-60 is continuously powered by the battery, and everything else- circulation pump, V-60, UV steriliser, battery charger by the (also solar powered) house power. One pump appears to be sufficient for all 400+ trout, at least with water temps around 10-12C.

On the back of the box are tank flange fittings, through which the pumped air is delivered to the mufflers, and then to the FT.


2 X 150AH 12V AGM batteries store the power for backup purposes, charged with (for now) a single 165W PV panel, or a 24V charger, which I have set to come on every 2-4 hours for 15 mins in the late afternoon and overnight, via the use of a programmed WEMO switch. With my phone I can turn the pump on at any time if it clouds over, and as currently set up, it will turn the charger off after 15 mins, so I dont need to remember to do it.
The battery box is a plastic box from the big B store, sunk into the ground for a bit of temperature stability, and I'll put some insulation over the top of it soon.

I went the cheaper way for my power safety only cost $5.

I plan to run all pumps and power from this box.

Fairly stable water temps recently, with a bit of a jump up on a warm early Sept day.
There'll be a bigger jump on Wed, with the temp likely to get to around 30C, and strong winds, so I hope there are no fires, as everything is getting very dry.

The WEMO is working well, and I'll probably buy another one for the small system water pumping, and maybe another one for the water pumping on this one.

I've just uploaded a 24MB 39 sec video of the trout feeding today, here:

http://gunagulla.com/organic/images/Vid ... arradd.mp4


It gets pretty frenzied in there, with lots of trout colliding with my camera holding hand.

There are more fine particles floating around in the water that I'd like, but with the addition of 5 new GBs soon, taking water from higher up than the exiting dual SLOs on the bottom, I hope to remove more of it. Quite a few of them still have fin rot, which seems very persistent this year. I've only lost one trout to it though, earlier this week.

Thanks Brian :) I was about to go out now to transfer a few trout to the small system, the Murray Cod has been alone for too long and there aren't enough nutrients for the new plants that need to go in now.
However, there's a pH 0.8 difference, so I'll give the big system a bigger dose of KOH tomorrow (normally 100g/day) and transfer some trout tomorrow evening.

I just had to go back to the beginning and see the expansiveness of this system before it got all grown in. Thanks for sharing your builds with us Gunagulla.
