Is your pH buffering well with iAVs? Have you needed to add any supplements? Are you all still happy with iAVs and finding it better and easier than your previous systems?
This is not our system, but one of our clients. We do add supplements in most of our systems, especially in winter which we're in now. No real issues with pH which over around the 7 mark and just below. Still very happy with results of IAVS when compared to Aquaponics
Great and educational but could you please allow other African countries to participate in this program to help in food sufficient for all Africans. Thank you for the consideration in advance.
I am not quite sure what you mean. This project is in Mozambique, and African country. The farm was built with their own initiative. Of course, any body from around the world is welcome to visit them and attend a training course. Training course is of course not free.
we are based in South Africa and offer training in Johannesburg. Next course around August 2024. Alternatively you can buy our ebook here henrikiko.gumroad.com/l/aquaponics
Thank you for sharing. The demonstration at the end really helped understand the process. This may help in my situation where a small or varying about of water from ram pumps are pumped to a tank at a higher elevation. Then with an undetermined amount of input water, which can be slow at times, we wish to release quite a bit of water to multiple sprinklers to water pasture. Thanks.
Thanks for the feedback .That’s a very interesting setup you have going there with the Ram pump . Will be very interested to know if this works in your system
Yes, in one of the videos we explain that the water pump is controlled by a timer, so around 30mins on and 1 hour off for the whole daytime. Can be turned ff at night, or left on as per same on /off periods
This is a brilliant build! One mod i can add is to control the water height by adding a string tied to the bottom of my kit (or rock for that matter). It can drain early if i make it short. Thank you for generously sharing this!
Thanks for the feedback.. Yes, others people have suggested similar advice to yours, a physical float stop. That could be as you suggested, or simply a wire or other physical barrier on top.
I might have missed it in the video, so forgive me if I am a total idiot. This is a great system, but I assume you put this in a control module and not in the same area as the grow bed where the media is? i.e. how do you handle the media getting into the box and weighing it down? The Bell siphons are inconsistent or can be, but they are also in the grow bed. I LOVE the idea of having something that will work consistently. I saw the video segment where the siphon that was operational for 6 years was working, and it looked like it was in a control module instead of inside the bed itself (i.e. no media around it that I could see)....
hi Mark, so yes you can install it in the grow bed or outside of the grow bed. If in the grow bed then you have to have a media barrier frame all around it to prevent the media (i.e. stone or leca) from obstructing the operation of the float. We use a strong plastic crate. The crate allows water through, but prevents the media from getting into the float area. Hope that answers your question ?
Tanks is actually full of fish, though still small when video was taken. There is a follow up video of when this system was converted to a flower growing system, where the fish had grown much larger
@@MyAquaponics1 not sure you got my point, the tank looks empty of anything except other fish. We know fish are reasonably intelligent so it must be very boring for them to just go in circles.
Hello! I am an electrical engineering student, and I am working on my final project about automation of aquaponic systems. I would like to create an automation project for the production plant shown in the video you presented. Would it be possible to send me the 3D model used in that video?
Thank you. Yes correct, much easier to add a physical barrier to stop the float at a certain water level, instead of trying to calculate the length of the flexi pipe
Hi, unfortunately our aquaponics and aquaculture courses are not online. If your interest is aquaculture, then we can put you in touch with Papa Pesca in Mozambique. Aquaponics and Sandponics courses are in Johannesburg
They germinate some of the seeds in the seedling trays which they then transplant to teh sand beds, but some seeds are also germinated directly on the sand beds
Thank, every DWC system requires two types of filtration. Mechanical filtration to separate the solids and Biofiltration to convert toxic ammonia into nitrates for the plants. Bioballs are for biofiltration and the brushes are in the mechanical settlement tank to trap any floating solids
Very interesting. I am looking at this for tropical Asia. Water is abundant so I see very little need to pump it back into the fish tanks. It seems like I can skip the biofilter if I pump it into ebb and flow gravel beds. What if I use the water from these tanks for the deep water culture further down? Will it be too lacking in nutrients then? Also wondering if I should skip those Deep Water Culture beds further down, instead opt for drip feed beds on the ground. I can then add other manure there if need be. Also pondering if I should do azolla and duckweed somewhere in the system. Seems like it would take years to test out the optimal system. Guess I should build one greenhouse, then start with 1/4 of capacity to test it out. Then build out the other beds once I have something that works. The glass fibre beds that work both as ebb and flow and deep water culture is a genius move btw. Standardisation is the ticket.
Yes if you have ebb and flow media beds you can get away without a biofilter, all dependant on fish stocking densities.. Yes, you could use drip irrigation instead of DWC. Personally I would go with sandponics (sand grow beds).. Have a look at our Sandponics videos (Part 2-4) on our youtube channel. We do let duckweed grow on our DWC to feed to the fish .
owsome aquaculture technology..how nany days upon pairing of breeders to collect an egg, how many time shall be the collection before conditioning? thank you.😊
No, you don't need a siphon with Sandponics.. Please refer to the "Part 2 Sandponics" video on our youtube channel to see how we made the outlet. Flood and drain cycle is controlled by a timer. Of Course, no reason why you could not use the solution on this video in a Sandponics bed if you don't have a timer.
No need for extra filters. The sand handles it all. Hence why it’s simpler and cheaper to build than an aquaponics system . Of course nothing stopping you from adding extra mechanical or bio filtration if you want , but in our experience absolutely not required
Hi, I'm a bit late to see this very educational video. May God bless you. So I just need to get going, and get started building this kind of commercial aquaponic. So my question is, roughly how much money should I collect to build the whole thing. Also I'm in Gauteng benoni side, maybe you can suggest places to purchase the whole equipment. Thank you so much.
Hi, thank you. We sell most of that equipment, including water and air pumps, PVC liner tans and fiberglass growbeds.. You can contact us on sales@myaquaponics.co.za or visit our website www.myaquaponics.co.za. If you are serious about aquaponics or sandponics, I suggest you attend our next course in Lanseria on 16 March. You then also get to see our system in operation.
Yes, anybody from around the world is able to participate in the program , but of course there is a cost involved.. Welcome to email us at sales@myaquaponics.co.za with any questions
Sorry for being pedantic, but this is not truly a siphon, it’s just an automatic drain. TBH, siphons can be tricky to hold a vacuum, so this auto-drain design is far better NOT being a siphon
No problem.. Technically you are correct as a siphon by definition must work with a vacuum. For us, the naming of this solution was more as a comparison with the bell siphon, and potential alternative. Thanks for your feedback .
Super idea. Thanks a lot for sharing. The flexibility of the flex tube may vary over time (temperature, UV light...) resulting in a change of the water height in the growbed. If you want to define the top waterlevel in the growbed exactly, a simple nylon string or twine attached to both the floater and the bottom or a heavy weight might do the job.
You are correct. In fact another viewer of our channel suggested something very similar to yours. A simple float stopper to keep the water level constant . Thank you
Silica sand is best between 0.5mm and 2mm grain size but can be expensive. We used a washed river sand . Either way always first do all the sand tests described in our videos
FILM TIP: If it's going to be a "talking head" video, just let the head talk in front of a stable background. Don't try to spice it up with fancy green screen effects. I had to stop watching this because the constantly moving background panning around the greenhouses gave me motion sickness.
Nice. Yes the bell siphon adjustment needs to be precise (for each bed, I have 4 beds) else all hell breaks loose...lol. I want to make this and test. My beds are currently operating without issues BUT I am not using a bell siphon...just a stand pipe for the water depth and then a 500ml coke bottle with cap on, cut to the correct height....works 100% all the time without assistance from me. I gave up on bell siphons. But I am always looking for another way. I actually want to make my 4 beds into 1 large bed so there would be less pipe work.
Thank you for your feedback and for sharing your story. I have seen the hack of using the bottles to emulate a bell siphon and they do work well as well. But yes, if you want to convert your 4 beds into one, the float siphon may be a more reliable solution.. Good Luck.
Water is water loss due to evaporation in such system? In DWS, water is covered and majority of water evaporated would deposit and drop down again in the water thus lessening the lost. Also, for one bed how many fishes would require to produce the waste?
We do not measure water loss due to evaporation as we always have plants in the system.. Total water loss is a combination due to evaporation plus plant uptake. Plant uptake varies depending on climate, type of plant and plant life cycle. We top up daily based on a level that we mark on the fish tank. Calculations to work out feed required to supply enough nutrients is complex and explained in our aquaponics ebook. Specific formulas calculate that. Its also not about the number of fish but the biomass of fish per 1000 litres. We keep it on average to 25Kg of fish per 1000 litres
@@MyAquaponics1is this the stocking biomass or harvesting biomass? Kindly help. I have a 5000L fish tank. How many fingerlings of 5g should I put this tank? Kindly help please
@@ernestbwalya5572 Max stock density is 30Kg of fish per 1000 litres. Number of fish is dependant on the average weight of fish. Keep in mind that if you add 30kg of fingerlings, that you will have to remove some as they grow
