14th November 2010 update : Here
I have been wanting to try out Barrel-ponics system by Travis Hughey , this system which make use of recycle plastic drums for Aquaponics are among the early setup widely tried by Aquaponics enthusiast everywhere.
If you check out Travis site, their barrel-ponics make use of half barrels as growbed.., fish tank using barrel and water feed using a barrel with toilet cistern type flood and drain.
The one I am making may be on a different approach toward barrel-ponics where I am just using one barrel making the entire setup with it. This approach is already done by others, the one I saw uses loop siphon so I am making this one with my mini siphon.
Additional Note :
I am downloading the Barrel-ponics Manual to check whether this setup I made is actually a Barrel-ponics system, because from what I understand Barrel-ponics is a system and not just by using these Barrel as containers it could be classified as Barrel-ponics.
After having read through the Barrel-ponics manual, I concluded what I build here is not a Barrel-ponics system.. its just a Siphon Flood & Drain Aquaponics using a barrel.
Bought a blue barrel from local scrap yard for RM 35.00, that about USD 10.00. It may be a bit overprice but I just wanted one and I've never bought any before. BTW these barrel are widely use here as pontoon, so the guy that sell me this ask whether I am making a pontoon. It will takes half a day to explain to him about Aquaponics, so to cut the time short.. I said yes making a pontoon.
This barrel already been washed internally but have a bit of a smell, Blue barrel normally use for storing non poisonous chemicals. The black color barrel is the one we should stay away from.
Barrel cut to my required size, let it dry out in the sun. Its been very hot and will continue later on with cutting the access on the lower barrel and drill hole for my siphon on the growbed part of the barrel.
Cannot go anywhere today.. its rain so I proceed in doing a bit more on the setup.
I've make cutouts on the lower barrel for access and stack the growbed part on top of the lower barrel. I use cable tie to hold the top part to the lower half. These barrel are made to be stackable so not much of a problem here to have it this way.
I may have made the cut out slightly lower then necessary,, this will make my water level low and may at time fill to the brim.. well just have to see and find out.
Additional note :
I should have cut the access hole the size of A4 paper one on each side, its better as compare to this one which is slightly bigger.
Mini Siphon stand pipe in place need to adjust it height next, its more to the side then in the middle, this is due to that uneven part running across from either barrel outlet. A flat place is essential for siphon stability so I have no choice but to have it here.
The point marked "X", I am thinking of making a hole for water inflow feed. I am still contemplating on making this hole or just have the water feed coming from the side to top of growbed.
Bottom of growbed, this show the siphon outlet.. its my mini siphon .. and due to its small size this setup will need a very small pump... I may use existing pump the 1000 L/hr rating and have a bypass for excess water returning back to tank.
Since this part of the barrel will be the growbed... its best to seal the two barrel inlet with a good sealer. I use Selleys' All Clear Multipurpose Co-Polymer Sealant for all my Aquaponics sealing needs... I believe its an Australian brand... so far I can say its the best I can find here in Malaysia.
Put everything loosely in place to test it. I use 1000 l/hr pump with lots of leak at the pump output giving a slow trickle in flow to the growbed.
Water in,, and slowly filling in the growbed, mini siphon is a rough installation. I need to adjust its length to cover the growbed height.
Not much of a guessing game on the siphon it flush first time, the more important is whether it cut off the flow.
Yes it does cut off without problem, this is the water level when it cut off. I need to redo just on the siphon and water feed inlet. Its a temporary installation which I need to redo later. In the mean time I will let it cycle and may put mild detergent to clean this barrel further.
It quite a simple thing to make, and took me approximately four hours to get to this stage, that inclusive of the time to make my mini siphon.
Total cost so far up to this point RM 80.00 thats about USD 22.00
Next will be putting gravel and let it cycle.
Note : This single barrel kit has been totally redo. The siphon use is the 20mm mini siphon which proven to be more reliable that a 15mm unit.
