Sandponics Part 3 - Sand Tests & Forming, Piping & Pump Connections : 2021

[@mcautics3914]

So interesting, this is the way to go, love the sand ponics idea

[@shaunthomas247]

This is amazing. Thank you Henri for your videos which are an inspiration.

[@rsmanal-rumaid4285]

Good good very good Good information Thanks

[@willieneluheni2102]

Wow this is interesting. I remember the old pvc lined wooden growbeds from when I visited for training and later buying fingerling. Please update us on how the plants turn out. All the best.

[@MyAquaponics1]

Thanks, plants already doing well, next video we will show the planting and thereafter some photos on how well the plants are doing

Fish normally swim closer to the edges in a circular manner. Why didn’t you put the output in the center. Wouldn’t it be easier, less resistance to put the fish tank closer to the out put and let the gravity drain the system back? It’s a great design though.

[@MyAquaponics1]

Hi William, not quite sure if I fully understand your meaning. When you say output, I am assuming the outlet in the fish tank? If so the water pump sucks water from the fish tank via that outlet, up to the grow beds.. Water in the grow beds then gravity feeds back to the fish tank. I dont necessarily agree that fish normally swim swim closer to the edges in a circular manner. Not our fish anyway. They swim in random directions. Even in our bigger circular tanks they swim in random direction, unless we create a circulating current. In that situation yes, they will swim closer to the edges in a circular manner

GREAT INOVATION, KEEP UP YOUR GOOD WORK,

GRATITUDE 💥🐟💥

[@mad-_panda_-2029]

I'm a bit concerned about the water going to the fish tank. How regularly will it have to be cleaned because of sand particles? And is there a other way to reduce the sand going through the system?

[@MyAquaponics1]

Once the sand has settled practically no sand particles flow into the fish tank. So no need to regularly clean the fish tank at all.

[@simplysaida]

I realize the water looks dirty because it's new sand that needed flushing but it was unclear are you just going to let that silt settle in the bottom of the tank or will you pump out that first batch of water and flush the system with cleaner water before use?

[@MyAquaponics1]

We simply let the water circulate and it cleared itself over a few days. Very little silt at the bottom of the tank as most would have been sucked up to the sand beds and get trapped there

[@simplysaida]

@@MyAquaponics1 Thank you so much for the quick and thorough reply!

[@NAMDUOCQUY]

Wow, this is amazing. Do you use a Mechanical filter and a Bio filter ?

[@Andrei-xd1yg]

neat great looking job! congrats! and the music is great too haha Question: the DWC is also connected to the same fish tank as the SandBeds?

[@MyAquaponics1]

Thank you.. No, the DWC beds you se on parts of the video are not connected to the fish tank that is feeding the sandponics systme. DWC is a totally separate system to the sandponics system on the video.

[@philrohlf4029]

Looks more like what we call decomposed garnet.

[@MyAquaponics1]

Different countries, different terminologies I guess. The sand we used is mined out of river beds, hence the name "washed river sand" . Irrespective, it passes all teh tests and that is what is important. Use anything that conforms to the standard tests.

[@ghsfroberts5655]

Wood sand from a granite quarry work?

[@ghsfroberts5655]

Would sand from a granite quarry work?

[@MyAquaponics1]

we used a washed river sand.. Best sand to get is silica, but usually expensive..

[@yossefvalnium4282]

Can I use white sand beach for Sandponics?

[@MyAquaponics1]

Unfortunately not, has too many carbonates

[@yossefvalnium4282]

@@MyAquaponics1 What about River Sand and then after extracting those media, we disinfect them. How's that sound? I am currently introducing Sandponics in my former High School. That's why I need help from the experts. Thanks

[@MyAquaponics1]

@@yossefvalnium4282 yes it can work, just do the sand tests we show on our videos. The one with vinegar will determine whether the sand is carbonate free.

[@tianyangtang6108]

Any good aquaponic or sandponic company you can recommend in North America?

[@henripereira7253]

there are many aquaponics farms in the USA, that I have seen on KZbin and other media. I however dont know any that are doing Sandponics at scale..

[@karimhayes3134]

can i work on your farm looks like to much fun ...

[@MyAquaponics1]

we're not looking at employing anybody right now but you're welcome to visit

[@Goodellsam]

I don't know about not having much negative space to keep it form getting nasty without good oxygenation.

[@MyAquaponics1]

Dont quite know what you mean, but nothing like doing it yourself and seeing the results. Sandponics is not a new concept. Has been done successfully throughout the world for decades, on a small scale and large scale.

[@YeweeAun]

How big is your water pump

[@MyAquaponics1]

we used a centrifugal 0.37Kw pump , 65l/min,, All you need is a tank that can change turn the volume of water on your fish tank at least once per hour or every 2 hours

[@YeweeAun]

@@MyAquaponics1 thank you

[@ernestbwalya5572]

​@@MyAquaponics1what's the size of your fish tank?

[@MyAquaponics1]

@@ernestbwalya5572 1200l which is too small for the 3 grow beds as I had indicated on the videos.. Ideally we should have used a 2000l fish tank

[@ernestbwalya5572]

@@MyAquaponics1 was the pump not equally too big for your system? My calculations tell me it should have been 15L/min... 1200Lx25%x3(assuming the target is to pump 25% of the water in 20min).. From what I have been gathering so far, the grow beds should have been 2.4m3 in total?

Nicely detailed. Musical style is monotonous and annoying

[@MyAquaponics1]

Thanks, yes, not easy to find non irritating royalty free music that is accepted by KZbin, but will strive to get better music for future videos

[@keifervitalis1830]

@@MyAquaponics1 Thanks. What you have going there is really great! And would be further enhanced with inspiring, uplifting music! I was wondering how long the sand bed would last before being overwhelmed by the organic matter from the fish waste thereby restricting the flow of water to the sump tank.?

[@MyAquaponics1]

@@keifervitalis1830 Water flow does not get restricted due to the way the sand is shaped with the furrows and ridges. Also no need to change the sand, as microbes establish themselves to fin inorganic and organic compounds. Some people have been running their systems for over 6 years without ever changing the sand. Sandponics or IAVS (Integrated Aqua Vegeculture System) has been tried and tested with great success. We're simply following the leaders in this industry and its working wonders for us. Egyptians are now doing it successfully on a commercial scale. You can also google Gary Donaldson who has been our virtual mentor.
