IBC tanks

[samtheman]

I was wondering if any of my central florida friends know or have access to 275 or 300 gallons IBC tanks. I am contemplating the idea on making a CHOP system which utilizes only one pump.

I have seen these being sold for a lot less than $100, but here you go: http://orlando.craigslist.org/grd/1946820588.html

Take a look. There is one in my city for $75, I may have to grab one since it's down the street! LOL

just bought one (275 gallons) from craiglist for $50.00 dollars....not bad at all

Be sure you know what was in it before you got it. Often they are used for pesticides or herbicides and would harm your fish & plants.

I was thinking about that also, this one had vegetable oil, about 2 gallons on the bottom....I still need to clean it really though

Wow Sam, you got a food grade for $50.... :mrgreen:

Do they have more....?

Awesome! Did you talk him down or was that the asking price? I wanted to try this kind of system, but my design concept was quickly inflated by my aspirations for a commercial-sized aquaponic system.

[samtheman]

He only had two for sale and I bought the last one, and that was the asking price :D ... to get it to my screen porch is been a nightmare. The plastic tank I had to bring it through my other living room double doors, then through the hallway with a 1/4 clearance and my wife screaming "don't scratch the walls" :roll: Now the frame is too wide to go through the hallway :evil:....Now my plan is to remove part of the screen in my porch, bring the frame in and close it back up without my wife calling 911 :lol:

In my job they have some 275 IBC tanks with bio diesel almost 1/2 way empty, I don't know if they can be use for aquaponics but in a month from now it will be empty.

Not unless it's pure veg oil. Typically, there are carcinogenic chemicals mixed in as thinners or some form of stabilizer.

I may have found some that don't cost too much......they have FLOURIDE in them. I was told they will rinse them out. (they are trying to save/use the flouride)

:?: ...What do you guys think....?....will they rinse (pressure wash) clean and be 'safe' to use ???

I would clean and rinse it several times. There are 3 main Fluorides used in water treatment and only 1 is liquid, H2SiF6. One option would be to scrub the insides down with a brush and baking soda. Leave the layer of baking soda all over the inside and allow it to dry. Then brush off as much of the white chalky stuff as you can. A better, but more expensive option, would be to get activated carbon or charcoal and crush it up into a very fine powder. Use a brush to brush the insides the same way. The carbon will absorb it and you can simply rinse it off thereafter. Since plastic is not porous, this should work quite well.

All-in-all, it depends what kind of "Fluoride" was in there. If you pressure wash it and there are still trace amounts, most likely it would not be enough to harm any biological systems it comes in contact with, including you. Fluoride compounds commonly used are quite water soluble, which means the more you use the system, the less and less Fluoride there will be floating around in it anyway.

Hope that helps! :mrgreen:

In your guys experience do ibc container plastic need to be covered to prevent algae? Or does it not allow that much light through

I had to use insulation on mine because the Algae was building up too quickly, I had some foil insulation leftover from a project that I have gotten from Lowes :
