I think they are $218 each. Wired isn't really an option here, but the WiFi works well from 45m away for my original system, and 10m for the new one.

with that foam.. did you work out what it was... was it from something in the potting mix. Eg. Wetting agents,



The potting mix is certified organic, so there should be no wetting agents in it.

I did some tests this morning, water in a bucket and added material to be tested, then agitated vigorously by hand:
lucerne hay - certainly frothed up quite a bit, but disippated within 20 or 30 sec
Potting mix - couldn't work up any froth
Sandy loam, cow poo, coarse sand, sawdust + compost from ANL - minor amount of froth that vanished very quickly
Searles Organic 5in1 - did make a bit of fine froth, but only persisted for less than 1 minute. However there was some fine white stuff which was associated with the froth in the FT and ST. I tried adding some hay to it and agitating again, but that seemed to decrease the amount of froth.
Rectangular beds not yet rinsed out, in case of residual release agent or other stuff left over from manufacture - agitated some of last night's rainwater, zero foam
Soil from around where transplanted citrus trees were that is very hydrophobic, which my wife may have put some wetting agent onto some years ago - no froth

Conclusion- buggered if I know where it is from/what is causing it

It could be that the froth is the residue from what ever it was that the tank was holding. Where I work, we have chemical barrels that supply our industrial washing machines. I've taken a few of those barrels home before, and cut them up for random projects. Even after TONS of washing and rinsing, they still produced foam. I recommend calling the guy who sold you the tank, and find out what it had in it before. Because as you already know, there is only so much home exploration will reveal.

Just my 2¢ after a day of work and school, and with a tired mind. So I apologize if this makes no sense.

They didn't contain anything before I had them, everything was bought new, some of them were only manufactured a couple of weeks before I got them, so it is definitely not left-over residue from any prior use.

I have no idea what is used in plastics manufacture, but if I recall correctly, pva release agent for fiberglass work will foam some. Not really helpful, i'm sure, but i figured it couldn't hurt to mention it.

Really impressive system, btw. I really like the looks of your plot, makes me a little jealous.

I don't really know what they use for a release agent with HDPE either, but suspect it would be waxy, which would sort of be opposite in effect to a wetting agent, and not really prone to foaming. Anyway, there is less of it now than last week, and I scoop more off every now and then, so I hope it isnt going to be a problem for the trout.

Speaking of trout, we had a visitor tonight for dinner, and he was very impressed by the flavour of the trout from my other system- and they have been in the deep freeze since Dec 2013, with the freezer set to max coldness to ensure they dont deteriorate.

3 rectanglar beds in place, although one doesn't yet have the temporary water inlet plumbing like the rest.

I'm running the Universal Pumps Sump Pump all night from about 9pm and only for a couple of 10 min periods during the day to try and lose some heat from the system. It's doing better than 2000 litres per hour (very rough calc) at about 4m static head (higher dynamic head, due to 15m of 25mm pipe). Ammonia now down to zero, but Nitrites maybe 2, or maybe 5, who can tell...the colours are basically the same. Nitrates about 10ppm, although they were higher a few days ago. Due to the Nitrites still being a bit high, I'll plumb in a 1000l tank to the system with the Murray Cod and put the trout in there for as long as required for the Nitrites to come down in the WB system, and hope the water loses a bit more of the brown colouration. I'll be adding a few more beds, but cant use my pool pump until I get the 4200l sump tank, which will probably be delayed by the ban on oversize trucks over Easter, so nearly 2 weeks wait for that, and I have to dig the hole to partly bury it.

I have to collect the trout on Mon or Tuesday, supplier is very unresponsive to emails- takes about 2 weeks to reply, but says I'll need live fish transport. He also said a month or so ago that they would be 50mm long, which I would have thought definitely did not need live transport for a bit over 1 hour trip.
Anyway, I have a 150 litre insulated box from B, and 12V air pump in case I need it.

Hey Gordon,

I just picked up 25 rainbow trout yearlings today from the trout farm (~200mm long). They put them in a large plastic bag that was topped up with pure oxygen and sealed off with cable ties. We sat it in a plastic trug in the boot and drove home 1 & 1/2 hours via the scenic route through the mountain ash forest (same time as highway route but much prettier). The trout were fine sealed in the bag despite the twists and turns through the hills. The trout were happy enough to scoff 4-5 large Skrettings pellets each an hour after being released into the FT.

I asked the guy at the trout farm if I needed ice to keep the bag cool and how to introduce the trout to the FT - he said no ice necessary as the day was only ~17C, and to just rip the bag open and put them in with no messing about. I did sit the bag in the FT for a while and then gently ripped the bag and mixed in some FT water for a few minutes before tipping them out. Worked a treat - hopefully they will still be just as happy and alive in the morning!

There's some photos on my system thread.

Good luck with your trout pick up. Your new system is looking epic :thumbright:

Cheers

Jo

Thanks Jo, that sounds reasonable to me, I really don't know why my supplier says I need live transport (for what he said would be 50mm fingerlings) - maybe he doesn't have any Oxygen. I'll phone him in the morning and hope to actually speak to him, rather than leaving a message with someone else.

I'v cobbled together enough fittings this arvo to make a SLO for the 1000l tank, and will divert one of the (3) GB returns from the existing FT to the 1000l FT I'll put the trout in. I'll probably position the SLO so the tank holds ~900 litres. If the trout are only 50mm long, I figure should be able to keep 250 of them in there for a few days (3.6litres of water per 50mm trout) until the Nitrites in the new system drop. I did a 20% dilution test today, and the colour still indicated 2/5ppm, so it looks like a week or more to go.

Wow, I must not be paying much attention these days! I did not notice this thread until you asked me to fix a typo. Now I am certainly going to watch it.

Hi.
We always got him on the phone no problem but by the time we were ready he had run out of fingerlings. We got them from another farm and brought them back in blue barrels in a van. 5 hours journey, with an airstone in each barrel, the airlines coiled in a bucket of ice and the aircon on. It all went well, in fact we could have done it with two barrels only ( or a lot more fingerlings ). You shouldn't have any problem only an hour or so, cheers.

I just spoke to Russell and he's flat out with Easter orders, so it's going to be Thursday or Friday before I can collect. I still don't know what size they are, as he says he hasn't measured them lately, but he says he can't put them into bags, so live transport it is! He reckons a couple of hundred will be ok in the 150 litre box I have. I'd better pack some towels as there will no doubt be some leakage/overflow coming back down the mountain from Hanging Rock, the road is quite steep.

Well 9am tomorrow is trout collection time, Russell only has about 200 fingerlings available, so I'll take them all :)
I have the 1000litre tank operational as an additional tank in the Murray Cod system, water temps have been around 18 - 21C for the past 5 days and I expect that to drop a little in coming days.

The asparagas crowns in the all gravel bed are already shooting up spears- amazing what a bit of water can do :) They've been in the ground for 2 years and produced very little, due to lack of water, but since their reccent transfer to the AP system, and having almost there entire tops chopped off, they are taking off. We'll just let them flower for a while before we start harvesting spears.
