Hi all,
Finally got round to assembling the new cod hole. Made from treated pine sleepers 2.4 metres x 1.2 metres x .8. Off tomorrow to get some old carpet to line the base and sides, then in with the liner. Followed by the joy of painting. Hell! I hate painting.
I have one growbed that I need to make a stand for, then I can get it cycling. The murrays are putting on some size and need a bit more room to move.
I have included a couple of pics of the work in progress.
Regards
Jonty
Nice work Jonty!
What size timber are you using? Ground treated for above or below ground? Tank dimensions? Volume?
Is there anythin in the base - or is it simply 4 sides sitting on the bare earth?
What stops the sides from blowing out with the water presure - just the bolts on the end?
Do you drive the uprights into the ground? If so how far?
Would be interesting to know approx material cost to build this.
Sorry for the 40 questions
Cheers,
Hamish
Hamish,
Treated pine sleepers H4 (inground certified). Just a box bolted together with liquid nails for extra strength and sitting on the bare earth. The sleepers are 50mm thick. No problems holding the 2160 litres. (Same as my first tank). 2.4 metres x 1.2 metres x 800 mm.
Two layers of carpet will be placed on the base and a single layer to line rest, then the liner. On a cold night - down to 6 degrees - I only lose about a degree through heat loss with the tank covered.
14 sleepers - $166.60
Screws, bolts and glue - $100
Carpet - free
Liner - $120
Top coping - $30
Murray cod swimming in it - priceless
Regards
Jonty
Excellent FG grow beds in the background Jonty....
Actually Jonty, it is a pretty good way to build a big tank. Those sleepers are available in 3 mtr lengths, so a much bigger tank is easily possible.
I assume the liner is just the commonly avbl "pond liner".
The only down side perhaps is that it would be a bit difficult to move if the need arose.
I wonder who made those beauties?
Hi all,
Finally managed to get back to the forum. Would definitely like to forget the week that has just passed.
Managed to get the tank finished and about to start on the growbed. Yes the growbeds are MH Mark 1 (or whatever).
Have attached the photos with the carpet liner, pond liner and the finished tank. Will have to remove the trim and tighten the liner a tad as it stretched in the sun.
Regards
Jonty
Lovely looking tank there Jonty.
Can you tell its capacity and how much it cost to put together?

Gary,
The usable amount it can hold would be 2070 litres. Internal area 2.3 x 1.2 x .75. I have a drain near the top for an overflow.
The final cost is
14 sleepers $166.60
Cuphead bolts, screws, liquid nails etc $100.00
Carpet lining (free from Carpet Call)
Liner $96
Coping $30.00
Paint $30.00 (Already had the paint from previous tank build)
Total cost was $422.60
Hi all,
Finally got round to plumbing the growbed to the tank. Have now started the cycle process. May take a bit longer due to the cold weather. I am trying the fishless/fish method to see if I can speed up the process.
Have also set up the ell-gro system from aquatic oasis. Will get around to plumbing it in shortly. Blasted cold weather, I need to get over my urge to hibernate.
Regards
Jonty
With the fishless cycling, just make sure you dont push the ammonia too high, or it will start to kill the bacteria, and take even longer to cycle.
That said, fishless cycling is the BEST way to start a system.
Good luck
