Backyard Aquaponics
A place to discuss aquaponics

I'm also feeling your pain.

Would a greenhouse have helped or gotten you over the line? What about the evacuated heat tubes you had?

A greenhouse would almost certainly have helped, especially over the last few days... of course today is another glorious day.. with temps pushing toward 25...

And a hoop house was planned after the fish were moved...

The primary move was indeed to move the Barra into the tank with the evac tube array... and the Silvers into the "hoop housed" system...

Getting the stock earlier would also have helped...

Close, so close... and to be caught out by a day or two is frustrating... c'est la vie....

Sorry to hear about your loss Rupe, its been getting colder by the day (8c at 5.30am this morning) my Barra tank was down to 18c this morning coldest its ever been and after reading your posts I better get my act together and get some heat into them soon

Surprised you've held that Daryl... I'd dipped to 18 for a day or two... but was holding 18/19 most nights... till the weekend... and it just crashed overnight...

As did the trout tank (6000L) down to 15.5... and the Silver Perch tank (1000L) down to 16 this morning....

Go figure... I thought the thermal mass of the larger tanks would hold the temp better...

I would have thought so to, I think the only thing saving me at the moment is that I am only pumping to the GB for about 6 hours during the day when its in full sun the rest of the time its just thru the bio-filter but it wont last much longer without extra heating.

Have you thought of putting insulation bats around the tank. I hear they are going cheap again now that no one wants them in the roof.

Was doing the same Daryl... and would have thought you'd be colder up your way...

What compounded things here was clear, cold nights... but cloudy (total), cold days... no heat regain during the day...

Yeah... but I thought they'd banned staples... how am I going to fix them to the tank....

The nights have colder than you I would say, but still having warm sunny days has been a big help,

oh what about a nail gun !

Sorry to hear things not going well, bloody sad.
John's barra have fallen in 1s and 2s, now 10-12 left from 80. My barra seem slugish and temp hit 13 a couple of times. Sitting at 16-17 during the day.
No I haven't finished the big system. It's temps have been higher a couple of degrees, but smaller range, so sunny days don't make much difference. Barra not taking food except when above 21. Ca't see if any dead, expecting floaters any day though. Luck has to run out soon.
Woke up last night 1-2 am thinking might need to attach hose to bathroom hot water tap and partial fill sump 100L to see how the temps are raised, say 55 - 15 = 40*100/1500 = 40/15=8/3=2.3 => 15+2.3=17.3
I'll try it tonight when get home from work. Need to be careful that sump not low (empty)

Of course today... the Barra tank is back to 20 degrees...

Hey guys you could always move to NQ. Beautiful at present ....

Here is my temps for the FT last night and 9.45am today ...

Too many queenslanders

Yeah... if the keep that up I might start up a tank insulation business... with a nail gun...

Blu-Tac dummy !
