Guys.... WE HAVE A SERIAL KILLER... :) Another failure with same symptom, wire damage. Look closely at the wire few inches from the pump body, sign of being nibble.
This is the second pump that fail the same way in the same tank, never had happen before. The tank was not new and I had pumps in it before without any problem. First it happen : Here as photo below.
Initially I thought it was the pump build quality, then could it be the wire chafe against the fibre tank. The pump has been use before and the tank is not new, no failure of this nature. I know rats love to chew on wire, sometimes we can find them electrocuted while trying to munch through the insulator. But this wire is underwater, and rat don't do scuba dive. One possibilities... its the Pacu that did it. Only this tank has Pacu fish and I only started doing pacu this year. I never had this problem before. Wiki on pacu : Here
Siphon installed a above, it's the same 15 mm siphon that I was experimenting for the last 1 year or so which I can safely says it's good.
Siphon close up.
Potted media in place for trial running.
Water inflow is a simple "T" with elbows on the end preventing it to slip and drop off. Water pump use here is Astro AS1000, which rated at 1000 Liter per hour with 1 m head.
The actual first flush of this setup, it works like a charm. The far end is water feed from pump using this style of coupling.
With instant plants from adjacent #guttergrowbed. This set I may use initially as a seed starter and once it has fully mature I will see what to do with it. One of the growbed I may not use pots, this is to test the siphon with full growbed setting.
We'll see in few months how this small simple low cost unit function.
Total cost approximately RM 160.00 that's USD 38.00 inclusive hydroton and pots.
Kailan in the #guttergrowbed getting bigger, altho they are generally thin by normal standard.
Only four pots of Kuchai in the gutter, and all are fine. Cut and gave away as usual.
Two pots of lemon grass showing good root growth.
Mint goes without saying, they had to be constantly trimmed to keep under control.
One of the rosemary cutting I planted earlier didn't survive, redo and wait.
Kailan in the CRAFTS set doing well too, there is one grasshopper feasting on it. Only one, so it's ok. Don't think this little fella will eat much after all, as long as it doesn't "call home" I'm okay with it.
Cili Bara producing chillies as they should, has to keep a close watch on fungus infection.
Making a mini #guttergrowbed set with a barrel as fish tank from surplus gutter that I have laying around.
Leeks surviving and showing root growth, will wait and see what happens.
And last but not least, I bought a flower pot stand, those waist high unit. It's for me to work on potted growbed without having to strain my back doing it at ground level. BTW.. The haze is still bad, it starting to affect my aquaponics plants.
Making a small single barrel #guttergrowbed set from surplus gutter. Six feet of gutter leftover from earlier set cut into two and endcapped.
After hot glue the ends, do a leak check to ensure all in good order. I had to redo and check it few times due to leaks, but the fix is simple enough to do.
Two 3 feet gutter resting on the barrel, this is one of the remaining barrel that I use for the craft barrel set. No additional support required as long as small plants are planted in this #guttergrowbed.
I intent to put pots in one of the gutter and direct hydroton in another to test out. Since it's small, it will be easy to clean if needed. All that's left to do now is installing the siphon and water pump.
Magnesium Sulphate (MgSO4) or commonly known as Epsom Salt are use in agriculture to promote chlorophyll production. Certain plants like Tomatoes and Chili require magnesium for their better growth.
Epsom Salt is non organic, so if your aquaponics setup is on an organic track, you have to think twice before applying this to your set.
Looks like sugar and it is highly water soluble, application as a foliar spray is common. In aquaponics, adding to growbed near the water inlet is recommended.
You don't have to add much, one table spoon is enough for a medium size growbed. Monitor for changes in the vegetable or plants leaves and only add if you suspect that the plants "green" is not as green as you might expect. Epsom Salt is also good as a relaxant, where you can add it to warm water and soak your feed. This is what most people use it for. In a bath and foot soak, they are suppose to have a relaxing effect on the body. So if you use Epsom Salt as a foot soak, don't throw that water away. Put it it the aquaponics set, so nothing is wasted. Where to buy Food Grade (Recommended) Most Reputable Pharmacy, like Guardian, Boots and Watson Non Food Grade Agriculture Shop, they sell in bulk.
Slugs, millipede, centipede, ants and other crawlies can start to be comfortable in the growbed. How do we get rid of them ?
On flood and drain media base aquaponics, I recommend to flood the growbed. Most crawlies can't survive underwater for long period.
To flood the growbed first stop the siphon action by removing the enclosure bell as photo below.
or remove the siphon cap on the #strainerbell siphon as below,
Once the cap or bell has been remove, the siphon action will stop. This depends on the height of standpipe will cause the growbed to be flooded. If the standpipe is lower than the media height, it is advisable to remove some of the media or change the standpipe extender to a longer extender causing a flooding.
Downpipe photo of the siphon as below with replaced extender.
Once the growbed flooded, wait a while and you can now see many creepy crawlies start to make their way to the top of the growbed. This is a good time to get your slug picking chopstick ready and start picking.
and more slugs
Well have fun picking those slugs.. :) How to get rid of ants ?
For ants, I recommend that the high water extender are left there for a few days, and let the siphon operated as normal. Then replace it back to the ones that have water 1" below media height. I recommend doing this flooding monthly, to ensure slugs etc don't have time to multiply. It is such an easy thing to do anyway.
I am an Aquaponics Enthusiast from Malaysia. My involvement with Aquaponics started few years back moving from water gardening, ornamental fish keeping and from necessities to keep plants alive in concrete jungle we live in.
Urban Agrostyle specializing in Media Based Flood & Drain Aquaponics using siphon, producing vegetables and fish for household use in the small space that I have. Ornamental Aquaponics is another area of aquaponics that I am looking at with working prototype that currently in use.
I did made some design improvement to the siphon use in aquaponics making it very reliable and as such that it is an "install and forget" item in the aquaponics system.
This blog is about my day to day activities in Aquaponics, trying out new things, improvement on old or just routine work that I do. It will also be some blunders that happens occasionally, so that it will be lesson learned and not repeated.
I am not doing Aquaponics in a commercial scale due to it require a different level of expertise, setting and support equipments, therefore I will not reply any query on it.
Enjoy your visit and hope it’s beneficial to both you and me.
