diy aquaponics plans


Cooling off for Larry & Moe
They like to have water pouring on their head. There are five left out of the initial seven, the two just disappear. I will need to get two males to replace those that is missing.

diy aquaponics stand | Crawfish Feeding Time Lapse

0

diy aquaponics stand


These Crayfish is very elusive and will hide the moment they saw me coming. I use the Samsung Galaxy S5 with Framelapse apps and leave the phone shooting for about 45 minutes at 1 frame per second.
Next time I will try not to feed them and get the camera ready before feeding, it may give better footage.






Anyway here is the timelapse footage.

diy solar aquaponics system | Crawfish Tank A 15mm StrainerBell Siphon

0

diy solar aquaponics system


It has been sometime since I last tried Crawfish, that time I was not ready and dont know what to expect of this crustasean . With some time to spare this afternoon and many surplus tanks and pipes, I decide to make a tank for it and at the same time making a small 15 mm siphon to test. Killing two birds with a stone.. as they said it.
I am using existing water source to water the new addition and right return tank as support. Surplus Dickson bars or angle irons make a rack using return tank as support. This arrangement make the distance for water return to be very small. It will be difficult to make a siphon.
Using one of the surplus smaller tub which already has holes in it for water inlet and previous 25mm siphon. The 25 mm siphon I use a tank adapter and pvc piping to make a stand pipe since I am not using this siphon, it is just to close the hole.

The other hole was for 15 mm pvc piping, this is just right for the smaller siphon I am  testing. I made this siphon same as the 20 mm StrainerBell just that it is using smaller parts.
The shorter return creates problem with existing fittings, I had to cut it to length so that siphon outlet just above water line in the return tank.
For now Im setting the siphon to operates at water height of 11 cm, no extender use. I do not want to use too much water since there is no hydroton in this tank. I think Crawfish dont need that much water, and having a flood and drain can keep them continuously supply with fresh water.
This siphon will drain water to about 2 cm, it is preset that way due to the vent on the inverted vent cowl used. BTW it is a 2 inches vent cowl and uPVC pipes, the 20 mm Siphon make use of 3 inches uPVC.
Thats the 11 cm water mark, hope Crawfish will not manage to escape.
Water inflow is a trickle, and I "tee" from existing feed to the right growbeds on my CRAFTS set.
Thats the completed 15 mm StrainerBell siphon and water feed.
Outlet flushing, I will need to test these. Since it is smaller the operating margin is much less. Water required is also very much less, making this siphon a good candidate for a gutter growbed system.
The completed crawfish tank with smallest siphon I made to test.

Next I will need a few Crawfish... :)

diy aquaponics shrimp | Tomatoes Going Ornamental

0

diy aquaponics shrimp


Done the mint test for my Ornamental set that uses the 20 mm StrainerBell siphon, on this 15 mm siphon Ornamental set I am planting tomatoes to see how this siphon stand against those deep rooting plants.
This lone strawberry plants removed and pot it separately to make way for fresh tomatoes seedling.
Sown these few weeks back and they are ready to be transplanted to the ornamental set.
Planted it directly to hydroton and bury it as deep as I can.
I put two plants in one planting space, I guest that overdo it since I do four planting space on this small set.
Oh well.., just doing it to the extreme.
Bad photos since it already dusk, will need to snap fresh photo again tomorrow and replace.

diy aquaponics materials | Testing New Pump For The Ornamental Set

0

diy aquaponics materials


Few types of pump tested on the ornamental set ranging from Alpha 1000, Alpha 500 and the Venusaqua E3302. Since I am trying to use the smallest siphon for the Ornamental set the Alpha 1000 and Venusaqua pump were not suitable due to the large flow rate.

The Alpha 500 works with the small siphon (15mm) but this pump construction make its maintenance high. The rotor is held by a shaft anchored at one end leaving the other unsupported and it is prone to cavitation. However it has been tested for almost eight month and still running. It only requires constant up keeping.

Test a different pump today a Sunsun HJ-600, an 8 watt pump with a flow rate of 600 Liter per hour maximum at zero head.


List of pump parts below.


The HJ-600 Specification.


The HJ-600 output verses height.


This pump has a front dial to adjust output. It does work, on my ornamental set with 15mm siphon I set it to slightly above the minus mark.


Side view, this pump is in 3 section, the front is the intake with the grille and flow adjuster. The mid section where the pump impeller vane and the front spindle support, with the back part house the motor coil and the permanent magnet rotor.


On the body it is rated at 10watt, oh well.. and the height max is 1.5 m, not bad for a small pump.


The other side of the pump.


Mid section after the grille removed.


The front part where the grille and flow adjuster.


To remove the mid section, quarter turn it anti-clockwise and it it detach from the body.


Exposing the impeller and rotor.


The impeller is different from Alpha series where this design reminds me of turtle climbing from a hole.


Shaft is stainless steel, to small for a ceramic but it is significantly larger that anything in its class. With larger spindle shaft pump will last longer.


Rotor removed exposing the housing which has a hols ad the beck for the shaft pivot point.


The back with hold for the shock mount rubber. This design should makes it easier to clean the mousing since we can have a water path right through.


All the attachment came with the pump, not in picture is a filler sponge.


Pump assembled, ready for installation.


Whats left not required for operation.


In the water and will be tested for few months under actual aquaponics setup.


First flush.


Water in rate as at slightly above the minus sign and only after prolong use I will know how good is this pump for this set.


There you go,

diy aquaponics water pump | Cali Who

diy aquaponics water pump


Its Calimyrna, I am a twig.. just a thin short twig from USA
Ok, so much for the twig bit.. Im trying out Fig. Got myself a Calimyrna Fig twig to try planting it here.
Dip the lower end in rooting hormone and pot it.
This variety may not fruit if it requires that special Fig Wasp or a male plant. Just a test for me and see. Will takes about 2 years to find out, that is if this twig survive the equatorial heat.
