diy aquaponics pdf murray hallam | Segregating The Fishes

0

diy aquaponics pdf murray hallam


In the CRAFT set, Tilapias and Jelawat with other fishes are mixed together. This obviously not good since some fish are aggressive and even among the Tilapias, the bigger fish will fight off the smaller ones for territorial right.


The fish has to be segregated and redistribute between the three tanks. 


Water in the tank that I need to catch the fish first is reduce by pumping it to another tank with the growbed filled up and preventing it from flushing.


Once water level has been reduce it will be easier to catch those Tilapias.


All the fishes are place in the center tank (Feeder tank) where the pump is located for later selection.


The bigger Tilapias is placed in the right return tank while the Jelawat and Patin in the left tank. The center tank will be for smaller juvenile tilapia.


While I am at it, why not scoop up few dirt, and and pebbles from the fish tank too since this is the best time to do it.

Transferring water from one tank to another ensures I do not waste any in the process of reducing the water level in the tanks that I want to catch the fish.

All in all it takes me an hour to do the tanks and transferring the fishes to regroup them.

zrumplina diy aquaponics | Lemon Grass in Container Flood Drain

0

zrumplina diy aquaponics


Serai or Lemon Grass is a common herb to most home gardener even in temperate countries where they would grow these indoor during the winter months and take it out in the spring. I did grow these in my growbed before back in 2010 or so but it just got wild and difficult to contain within my growbed.

This time I want to do it differently by using the slotted orchid pots, hopefully it can be "tamed" to within the confinement of the pot. Got myself few stalk of lemon grass which is easy to get and just let it stand in a bowl of water for couple of hour or so.
Since Im doing it Aquaponics, a couple of hours is sufficient and dont need to wait for roots to form like when you are doing it with dirt.
Three pots and using some surplus hydroton and pebbles mixed as grow media I prepared six stalk for planting.
Two in each pot, just in case one didnt make it. But it is highly unlikely for this not to grow. Over here this is easily grown anywhere.
Placed the pots in the growbed and just wait. Ideally for this plant it is best to get a larger pot like twelve inches across, those pots is only six. Ill get a bigger pots once these shown good progress, on average Asian household we probably can make do with two pots of these for our daily cooking needs.

easy diy aquaponics.com | This Years Balcony Garden attempt!

0

easy diy aquaponics.com


Good crop of tomatoes, no aphids since i planted lots of onions and marigolds, Blackberry bush has grown huge and still growing had to use an old clothes drying rack as a growing frame, Installed a new drip irrigation all the way around balcony from my 100liter water tank with the help from my grandson.
Biggest obstacle has been getting supplies to my apartment, carrying bags of growing mix and compost by bus is a pain to say the least, oh well at least its exercise. I am lucky with that i get 6 hours plus of sun on the balcony, but the winds can be a destroyer drying things out and breaking my tomatoes.

diy aquaponics aquarium | Slotted Pots For Potted Flood Drain Aquaponics

0

diy aquaponics aquarium


Starting to do more of this potted flood & drain style of aquaponics since it is very convenience and use less LECA. There are pros and cons for doing it this style, however for smaller plants it is ideal and could be one of the best way to do it.
Slotted pots, not sure whether it is a net pot or not but its look good for what I going to use it for. At Rm 2.50 each,  they have slots that is better at draining away water and root growth.

Update : Just found out that these pots is for Orchid plants, so they are Orchid Pots.
Six inches across with no other sizes available from nurseries at Selangor Green Lane, for what I am doing it is sufficient.
Compare to the normal plastic pots, these has more holes and it is just nice for LECA since the slots are narrow but many it will give good drainage.
Just nice for LECA
These are not recommended for large plants, most leafy greens is okay.
Doing one Strawberry since yesterdays almost all I had redo to pots. Ill use this for future potted flood & drain style aquaponics.
Now just wait for these to grow.

diy water pump in aquaponics system | Potted Media Base Gutter Growbed Siphon Flood Drain

0

diy water pump in aquaponics system


A year back I did emptied my growbed and uses pots to grow Gandarusa plants, this method of planting utilized much less LECA and make it less costly to make a bigger set if needed.
It did grow well for the Gandarusa plant, its long overdue that I wanted to try this method on other plants.  This simpler setup may be more viable to do on a larger scale with minimum changes to existing media base siphon flood & drain technique.
I had done gutter growbed in 2010 and its at that time was difficult to control its flood and drain reliably. I was using loop siphon due to the confine space of the gutter and it was not successful in planting anything significant.
I am giving it another go, this time I will use my 15 mm StrainerBell siphon on left as photo above. It is the smallest siphon that I had done and after tested it for almost a year, I feel its capable of controlling the flood & drain within the confines space of a rain gutter.
As a trial setup, I decided to do a simple gutter growbed setup, that could accommodate up to 9 or 10 pots place over a fish tank. This arrangement suit the small space that I have.
The gutter was kept for a long time, I got it in Nov 2014 to do this setup. Unfortunately due to the problem I am facing during that period has kept it on hold until today. Above photo I was testing the gutter for leak, I will use only two.
Made a rack for the two gutter over the fish tank from leftover dickson bars and had to join them making a longer piece.
Water feed as usual "T" with 1000 Liter per hour pump feeding the two gutter. Water head is about 18 inches.
15 mm siphon, making it as short as possible, water level is less than four inches.
This siphon has been tested on my ornamental set and had survive a full growbed rootball without failure. So I feel its time to use it for this set, anyway this is the smallest I can make.
First flush test and as you can see from above water is not level, this is because the front part of my house is slanting. I will need to adjust the rack to take up the gradient.
The rack has been adjusted, see the different between the far and the near end tank to rack gap. It is about two inches different in height to add up on the far side of the rack.
Siphon in between the pots, I will use LECA in the pots surrounding with flood & drain water. This style reduce LECA usage and we may use pebbles too at smaller quantities making it lighter.
Water feed is at one end of the gutter with siphon at another, trying to create a nutrient flow within the growbed and water movement in the fish tank between siphon outlet and pump intake.
It does flush well, will put an aerator outlet to reduce noise and at the same time giving much needed oxygen to water.

Okay, this setup needs to be cycle with fish and simple plants. LECA will go in those pots next and will get some cheap fish to ensure no mosquito breed in the tank.

easy diy aquaponics download | Evolution Of The Media Base Flood Drain Gutter Growbed

0

easy diy aquaponics download


My ongoing quest for cheaper and easier Aquaponics set are finally coming to an end. The traditional Flood & Drain Media Base Growbed has to go. It has been more that eight years since I started Aquaponics, initially using pebbles or stones chip then to hydroton.


The traditional media base works, it does has its pros and cons as any other type of system in Aquaponics but the one that really hamper the progress of Aquaponics in this part of the world is the cost of setting up a system. Traditional growbed are relatively expensive to setup due to the volume of LECA needed. To do large scale is almost impossible due to this.


It is not so straight forward that we can design a system and walla.. it works and at the same time reduce the cost of setting up. It takes time to test and test.. and systems evolves from these trials. I specialize in media base flood and drain using siphon and I try my best to make a system using this technique cheaper and easier to construct.

I started experiment with mini growbed system few years back when I made the single barrel set to see how well a smaller siphon control the water flow in a growbed. As with siphon, the smaller it is the more difficult to get right due to very small tolerances it has to work upon.


The barrel set above uses my midi siphon, a medium size standpipe of 20 mm, it does work but not good enough to make it a cheaper setup. It still requires lots of LECA and only the size is smaller.


I had to make something that resemble a NFT set up but has a flood and drain element in it, that is when I started experimenting with the gutter growbed few years back.


Above in 2010 was my first attempt of a gutter system, the siphon use at the time is a downward loop siphon, and it doesnt work that well. As in the photo pebbles was use and most of the time it function as a media filled DWC which has limited plant type to be grown.

In order to get a good flood and drain, the siphon must work ! The problem with siphon is the smaller it is the more difficult to get it right. My 20 mm siphon is too big for gutter setup I had to design something smaller.


It was my daughter that asked me to make something for her "Show And Tell" she asked me to make a micro Aquaponics set that demonstrate the concept of Aquaponics. To make a micro set requires a micro siphon. That when I make the smallest siphon that I currently use, takes about 2 weeks for me to figure out the design proportion and further few weeks to test the proof of concept.


15 mm siphon is actually not new to me, it was the size of the first siphon that I made for my initial Aquaponics set, at the time I was very new to Aquaponics and the siphon is just a straight standpipe with enclosure to create the siphoning. Obviously it is not a reliable siphon at the time. But instead of pursuing the 15mm siphon I took the 25mm route to make a big siphon and improve upon the design until it is what it is today.


I tried the 15mm siphon on ornamental set for almost 2 years, being first make it debut in early 2014 and many test done using the 15 mm siphon that works beautifully. After extensive testing, only then I am satisfied that now I can use the smallest siphon to run an Aquaponics set that is easy and cheap to make.


This is when I started to make the #guttergrowbed system and to make it easier I didnt put the LECA directly into the growbed but uses pots to make it easier to handle. I was worry that the potted setup do not has enough surface area for effective biological nutrification processes, but it does do well it the initial test.


It is obvious the #guttergrowbed setup is not for large plants, but for commercial intent it is viable to have crop of smaller plants and leafy vegetable at a lower cost of setup.


So finally, the traditional growbed has to go and make room for #guttergrowbed at my back lane set.


These 4 gutters is 4 meter in length each replacing my 4 traditional growbed, trials shows that it uses only 1/5 the LECA for the same area and 1/3 the electricity to run it. This is possible due plants are in pots and siphon is smaller.

So this next few weeks Ill be busy with this retrofit and I hope it does work on a larger scale setup. The design and how to will be made freely available here as my contribution to the Aquaponics community.

The final part would be going off grid, which is easily achieve due to the low power requirement of this set up. For the 4 #guttergrowbeds it only consumes 30 watt of electricity total.
