For this project, you will need:

Two food grade 55 gallon barrels, one MUST be whole, bottom 12" must be intact (at least) on second barrel

a box of 1/4" by (1/2" long)Stainless steel carriage bolts (MUST BE STAINLESS STEEL) You wont need them all, but a box of 100 runs us under $8 at Ace Hardware (Try to support the little guy!).

A box of 100 staineless steel washers (about $3 to $4)

A box of stainless steel 1/4" nuts (under $7)

A piece of plexiglass (can be 1/8" the thin, cheap stuff) Ours was from scraps.

aquarium safe clear silicon (two tubes, it can probably be done with one, but get 2 just to be safe)

a small pond pump (we use 400 GPH pumps for our systems)

either a 10 foot stick of 1/2" PVC, or some scraps and fittings

two 1/2" PVC male adapters (slip to thread)

Two 1/2" PVC female adapters (also slip to thread)

A 3/4" TAP to thread a couple holes

a 3/4" hole saw and electric drill

A jig saw

A Sharpie (to mark out your cuts on the barrel)

some expanded clay or gravel (media)

A 12" piece of 4" PVC as a media guard

PVC cutters, or a way to cut PVC

A bell siphon (I wont cover that here, but there are a great many resources on this site, and you tube that will show you how to build one, and there are alternatives to the bell siphon that work well too.)

a 1/2" ball valve

I think that is about it.

Step 1: Prepare Your Fish Tank by Removing Top of Barrel, and Cutting Access Ports and Prepare Plexi Glass

Remove the top of the barrel, leaving a small lip inside of the top, to help the grow bed sit comfortably and use a ruler to mark out two squares on the top third of the barrel, ours are about 8 inches by 8 inches. Use a drill, to drill a hole in a corner of the marked area you plan to cut so that you can get your jigsaw blade in. make sure to make rounded corners to help the barrel keep its integrity. Remove any burrs left over after the cut. they can be picked off by hand, or a pocket knife works well also.

Now onto the plexiglass. I have found that the easiest way to cut plexiglass is with a jigsaw, mark out your rectangle, 11" tall, by 20" long, and put masking tape on the bottom side of the glass under your planned cuts. The tape prevents the plastic from fusing back together after the saw blade passes through making the cuts.

Once you have your 11" by 20" piece of plexi, mark out your bolt holes with the sharpie. I suggest going 2" apart, leave a 1"buffer between the edge of the glass, and the bolt holes. To drill the holes, I used a 3/8" drill bit. Make sure to run your drill backwards, and apply very little to NO pressure to avoid cracking the plexiglass. Once the plexi is drilled, remove burrs around your holes, and set a pizza pan in the oven upside down, preheat the oven to 250° Place the drilled plexiglass on the pan, and heat it for 5 to 6 minutes. It will start to sag a bit at this point and be soft enough to form. Using cotton gloves, remove the plexiglass from the oven, and place into your barrel, (make sure both the glass and barrel are CLEAN) and hold it inside the barrel for a couple minutes to make sure it forms to the curve of the barrel. Leave it there for about 10 minutes to cool fully before grabbing the drill again. It is now time to drill the barrel. Using the plexglass as a template, drill the middle holes on top and bottom of the window, and insert a bolt from the inside of the barrel to the out, and add a washer and nut. Next, drill out the holes on either side of this middle bolt, (top and bottom for a total of 4 holes) and add the bolts washers and nuts to these. Continue using this method drilling from the middle out and inserting bolts as you go until you reach the edge of the window. The side holes can all be drilled one after another on both sides and then bolts can be inserted.

<p> this system not need a bio filter..? the water pump need be stay On all day ? or what interval of time you use.</p>
<p>No, no filter. the grow bed on top is the filter. we do add some red worms to our beds as well, we also have heirloom seeds (and worms) available at www.madriverseeds.ecrater.com</p>
<p>Hello sr, your projetc is awesome, am trying to develope a similar system, I wanna know how much fish by Barrel are you using, and what kind of food you provide to the animals, and if the water pump is turned on all day, or have a timer cicle. </p><p>Thanks, for share</p>
<p>Thank you! We stock the tanks with about 10 to 12 large fish, or about 100 fry, and they seem to do well at that density. We order tilapia pellets online to feed the fish. The food we buy has no land animal ingredients. The pump is on all day every day, to circulate the water into the grow bed, and keep it moving and oxygenated for the fish.</p>
<p>It has been a few months, and now, an updated picture of what is going on in the barrel system.</p>
<p>How do you get a 55gal bucket?</p>
<p>Tree top is a good source, around us, they sell the used barrels for $5.00 a piece. If you try to buy them online, they will run you a pre4tty penny, usually around $50.00 or so.</p>
are you referring to the juice or the ranch named tree top
<p>The Juice. We have a few Tree top facilities around us.</p>
<p>well done. good basic ible. i have been &quot;aquaponic-ing&quot; for about 3 yrs now, this stuff is a blast. your barrel system is the best compact i have seen to date. however, my question is the bubblers in the lower right, is that a lactobasilic fermentation? of apple? i do not recognize the color of the product.</p>
Thank you for taking the time to comment! There are 3 carboys back there, the first is lemon wine without peel, the second is with peel, and the one back in the corner is hard apple cider.
