Backyard Aquaponics
A place to discuss aquaponics

I may have posted those before. Hmmm... you may be right on the wireframe tank. I seem to recall that thread.

El cheapo is an understatement. Two 8 foot diameter tanks were under $100.00. The only drawback was my redclaws ate through the lining on the folds. Because of that, i would probably go the epdm route next time. Don't think a seam would be too much trouble.

I did just find this... a supplier of heat exchanger tanks for solar projects. Looks like they use the folded method. Not for use with yabbies!!!

My memory is that I saw the photos on another forum

That solar heat exchanger looks cool.

Could be... I know it was posted on the soalroof greenhouse site and also on gardenweb at some point...

I am finding that butyl rubber is supposedly weldable. That would make things easier...Not sure if approved for aquaponics but i did see one site that say's it's approved in the UK for potable water storage..... might be a better way to go....

Decision has been made...

and its a secret

oh cmon you know that's not fair

we've all been on this journey with you together now

Don't know why you didn't go for a second hand above ground pool. My daughter got a really good one which included a salt chlorinator vacuum cleaner etc for $300. Its at least 18000l.
Just sell it when you move (buy in winter sell in summer).

I've looked at them as options but while a tank is a tank a pool is a pool even if used as a tank. That means I could get into strife from the council for not having pool fences and the like.

With a neighbour almost guaranteed to dob me in it is not a risk I can take.

I spoke to my Dad who is a bit of financial guru and he got all logical on me. Turns out the best solution is the Elcheapo because with my limited funds I should preserve my funds for other things that i am going to need to be spending money on shortly.

So I found a deal on a top quality liner I've been looking at for a while that is UBER tough with a 100 year or building life time warranty (whichever is longer). The hippy in me that objects to our disposable society couldn't face using greenhouse plastic for a tank even though I agree that it probably was the more sensible option.

This liner is weldable with a blow torch and roller so I'll be able to form it to the tank shape.

That means that later I can keep it as a storage tank or as a fish tank If I want

Normally this stuff is about $20/m2 but I got a deal

Hey Poppa, loving those tanks.
What is the middle layer of that tank? The one between the reo (re-bar) mesh cage and the liner?

Well, it's pretty secret stuff, normally sells for $1000.00 a square foot but my dad got me a real deal. I'd have to kill you all if i told you what military installation it was found laying around at. You just have to clean off all the depleted uranium dust on it, but i found a neighborhood kid who wasn't doing anything and was happy to work for a cold glass of kool-aid.

It's just fanfold insulation, the stuff they put on the side of a house before putting the siding on. Also, that "rebar" is just standard fence wire from the box store. bendable by hand. Nothing special.

100 years, Stuie? I hope you got that in writing...

I don't think they expect me to be around to make a claim.

This product has been used quite a bit in Europe but not much elsewhere. The only place it has been used in Austraila so far is in Gippsland.

When the Morwell river broke into the adjacent open cut coal mine this is the liner that they used to repair and stabilise the new river diversion canal.
