growbed, not sure if its galvanised

[nechaus]

for my new diy system, i had a old 100 liter worm farm tank, its made out of metal, im not sure if its galvanised yet, it has a grey color, im going to post some pics and see if any of you can identify it,

[nechaus]

it would have to weigh about 50 kilos i reckon, have to wait untill the missus gets home so i can use her iphone camera

[nechaus]

i have just read, most steels need to be coated,

I have a flood and drain setup, The actual Fish tank is a large plastic container 220L that is food grade, The grow bed the only metal part

is it worth the risk of using it?

[Hotrodmike]

I would not without lining or coating ,but then thats me !

Say if i did use it, would it be safe to eat the fish?

im thinking i may just go to bunnings and get a cheap 150 L pond

Yeah, better post a picture. If it was for a worm farm, perhaps its ok. But then, nobody wants to give you a bum steer :rolleyes:

Its best you ask first like you have, just will have to wait for the right advise after the pics. Cheers.

[nechaus]

ok, it has been painted on the outside,
i tried to get the best pics i can, but im not sure if you can tell much by it


What do you think?

In an ideal world I would not use it, but......I doubt that you will come down with some strange disease overnight. More junk, poisons and so on in buying supermarket , so called "fresh veggies"
Moving towards sustainability and better food is a step by step process and with each step improving on the last.

I hope to get one of your systems late this year or early next, cant wait!

[Hotrodmike]

I agree with Murray from the aspect of we all more than likely have way too much toxins in our system from just living . But then again I said I would not as I am trying to eliminate as many of those as I can . Looking at the pictures it could be oxidized stainless but then it also could be galvanized that is oxidized ,for grins try a magnet . Something that size I think I would just find something to line it . Thats just me .

So what are your thought left as is, if i added jade perch would they be healthy ? and if they stayed alive would it be ok to eat?

im trying to get rid of toxins to, trying to be as healthy as i possibly can.

i really want to buy one of murrys systems, i just want to learn more, and have the spare cash to i can go all out.. i wanna be able to provide quality food not just for myself but my entire family is possible.

[nechaus]

i just put a fridge magnet and it stuck on well,

[dufflight]

Magnets don't like sticking to stainless steel. I would put a plastic liner in it or some rubber paint they use on water tanks.

[nechaus]

ok well, i searched for about 30 mins trying to find a cheap rubber paint, was thinking ill use a pond liner and seal it up with that, looks like it will be the cheaper option.

i have one more question, it has been flooding and draining for about 24 hours, should i dump the water and refill the tank? wanting to put fish in the tank, maybe like 2 or 3 weeks once some bacteria has built up a bit, dont wanna risk any contamination for the fingerling's..

[Hotrodmike]

Sounds like a good idea .
I do not think I would be too concerned on the water being in for that short of time unless your PH is very acidic . I think part of the problem with AP is we run a very low PH ,compared to say aquaculture .That tends to etch the metals in a system leaching the bad stuff out . I do not think you will ever get rid of 100% of your toxins as they are in basicly everything including the water you drink. An all glass AP system with purified water might just be a bit over the top ! Cool looking till the algae set up house :D

thanks for your reply, yeah i know i wont be able to remove all the toxins, for e.g. the air.. but if i can avoid it i will, i really dont want any mercury in my food.

I went to bunnings this morning and got pond liner, stayed awake last night thinking about it..

god dam im dreaming about aquaponics to

[Hotrodmike]

Pretty much my thoughts ,can never get rid of it all but if I see something I can ,I do . Yup even the air is a problem but the biggest is city water too much stuff that does not get filtered out and too much added to keep us healthy ,boy thats a line !
Sleepless ,dreaming :( duh you gotta count fish to go to sleep now :D
Good Luck
