Backyard Aquaponics
A place to discuss aquaponics

Unfortunatly this goes hand in hand with heat loss from the surface catch 22

Doesn't it suck............

yeah. ya can't win em all. Gonna have a look at using seconds poly rain water tanks- food grade, and you can get them about 1.3 m high 2 metres around for less than $500. Cut segments out of the top leaving 'spokes' for strength, bob's your uncle!!
Looking for a bit extra height so I can syphon from the tank to the grow beds.

Why are the tanks seconds Monya - what is wrong with them? Sounds like a good option if such things are available at a good discount.

The price you are quoting seems pretty good Monya as the squat tanks are normally much more costly than the tall ones. A nylex 2160 diameter, 1450 height (inlet height 1250) retails for $1060. It holds 5000 litres.

Are seconds readilly available where you are Monya?

they are scratch and dent, cosmetic stuff which shouldn't affect us at all. Look at taking 40% off the retail price for a seconds item. I've got to go look at them tomorrow, see for myself what they are really like. As for avaliability, I rang all the local tank places today, and they had a variety of different ones available. I reckon it's just a matter of timing. Not sure whether to get 2300 ltres or 4500 litres.

Oh, yeah, I re did the water in the bucket of gravel test. 3.5 litres for the 10 litre bucket. Too much for my liking. Must shop around for different gravel.

Got a quote on a stainless steel tank. Round corrugated 304 stainless. 2000mm diameter, 1200mm high, no top, capacity 3800 litres (if filled to brim). Guess how much

Stainless???? Geeees two and a half to three grand would be my guess...

Way off. Try $800. Is well worth thinking about.

Damn that sounds very cheap........ Almost too cheap considering the price of plastic tanks.

yeh maybe

crazy cheap!!!!

VB, that's great if it is true.....It is less than aquaplate or gal for the same size
Where is this place ?
Murray

I will make some more inquiries - might even go and have a chat to the bloke to see if I can have a look at the product to see if it is of quality.

Will update in due course.

got one of the poly tanks today. 2300 ltres with a removable lid for $385. Just a few scratches. Also a couple of 1200 litre grow beds for $270 each. They are a bit large in diameter, but the right depth and they should be okay.

Well done Monya - that is so cheap! I doubt that they would discount seconds to that degree up here. There is a huge demand for water tanks right now so prices are at a premium.

Tell us more about the grow beds. Are they round like the tanks? How deep are they? What is their normal use?
