  3. Hi Benson and welcome to APN, Tell us more about how you are thinking about applying this to your situation. Some questions off the top of my head Are you thinking about just investing in a small home scale turbine and only applying it to your aquaponics or applying it to your home as well? How will you get the water flow needed to run the turbine? Do you have a river or are you thinking about some sump arrangement with a pump to create a head and flow? Do you have a suburban house or property in the country? On a whole of house scale, I don't have a country property with flowing water running through it. About 9 or 10 years ago I did think about a property with the view of adding hydro so I could stay off grid. The conclusion I came up with regarding hydro is you really need to be an electrician to be able to maintain the electrical side of a hydro plant, plus by the time you invested in hydro and the extra effort you needed at the time to run it it was easier to run on grid, so I did not continue my research into the hydro side of it. Like solar and solar energy storage things may of changed now. Co incidentally, if you are interested in looking at another alternative energy you may like to look at my thread called bigdaddy's alternative energy. I have recently posted what I have been doing in that regard. I'd be interested in what you do so please keep us posted. Cheers.
  4. Looks like I'm about 9 years late replying to this but this is a concept I think about constantly as well. Some of the big questions I have found are: -Is the flow (LPM) strong enough to turn a turbine to generate power? What is the minimum needed for this to be viable? -Will placing a hydroelectric turbine in the system effect bacterial colonization? -Is there a possibility of creating a terraced aquaponics system which will create greater head from which the water to drop and therefore generate a higher volume of energy? Additionally, one potential way to incorporate hydroelectric into the system is through the use of I believe what is called the Kaplan turbine. This turbine would operate as both a filter and through the vacuum it creates, a pump as well. All the while it could also be generating electricity, even if just enough to help offset some of the energy costs associated with running an aquaponics farm. If anyone would like to discuss this in more detail, please reach out to me. I am looking for others to discuss designing and building a proof of concept on this, what I have coined CLAEYS: Closed Loop Aquaponic Energy Yield System.

  6. HiJecha, What are all of your readings? pH Ammonia Fish tank temp Nitrates Nitrites. Also, if you could describe your system and maybe post it in the aquaponics systems section so we can see what you have in it, that would be helpful. Cheers.
  7. Hi everyone, Some more pics of my new backyard setup. All grass and dirt up and out, road base in, reo mesh and storm water set up ready for concreting. Concrete down, channel drains down, vibrator in ready to compact the base. 600 x 600 x 30 granite pavers going down. A snapshot of how my back and side corner will look with the fake grass down. I can put my fish tank and grow bed here with a nice drain built in to the set up if I wish. Chanel drains up and out and granite going all the way to the back fence, a much better look. Cheers.
  8. Hi! I just wanted to ask. The nitrite content in water of our Media Bed aquaponics is higher than the acceptable range of ppm, however the other parameters were desirable. I had check the possible reasons that might contribute to this problem. It might be the water spinach but found out that in some articles regarding about it says, it actually enhances water quality. I've been thinking it might be the condition of our charcoal filter. When does occasionally the charcoal need to change or replace? Your help is highly appreciated☺️.
  9. Hi Jennifer and welcome to APN, Typically the aquaponics we talk about here is using a RAS system. This means we have a fish tank( which can be filled by your water from your steam), with nutrients added by fish, then the water goes from your fish tank to a or some grow beds(bio filter) to feed your plants, then to your additional filters and returns back to your tanks. First of all the fish tank is cycled, at the same time plants are added to (typically media filled) grow bed and once the system is cycled the water is kept in what can be described as a closed loop. After some time the level of the water drops naturally, either by evaporation, transpiration, cleaning or all, then top up water can be added (from your stream). sometimes in a mature system if the testing is too high a partial drop( approx 10 percent) may be needed and a top up added. I like to drop the water 10 per cent occasionally. Hope this helps, Cheers.
  10. Hi everyone, I have started my iVAs with on a completely blank canvas. I thought I'd post my journey in some sort of chronicle order and maybe give some ideas for those who may be thinking about a system and/or for those who already have systems. I feel good planning is the key to building. I have spent many hours thinking sketching measuring and using whatever else I have at my disposal. My aim is to build and run the most efficient, productive system I can, making the beat use use of the space I have. I have several challenges. Below is a list which is not conclusive. I can break down these items to further explain but will not for now. Cost Looks Very small backyard Suburban living Weather Maintenance Time My backyard measures 4.8 metres by 5.0 metres Here are some pics from the the start. The original side with my beloved citrus trees with the left side 2 sitting on the slab where my air conditioner originally was. My new pergola. The original rainwater tank New slimline rainwater tank and system ready to be re plumbed and reinstalled. Air conditioner and rainwater tank installed around the side out of the way where noise and size will be minimized. My original line of thinking about a small iAVs system. Another view of my original backyard, this time to the back fence with the back garden removed. A more current view of pic 1, backyard opened up with all the screening up and roof addition to pergola. More to come. Cheers.
  11. Some pictures. Changing out the grow bed to a 6 by 3 by 7 inch deep, got one for free from a friend and since the new baby can’t be spending a lot! But here’s some pics
  12. So i am worried I may have to change my grow bed size. Right now I’m using a ibc tote for the fish, the water leaves through a bulkhead fitting in the side, to a 4x 8 foot grow bed, this grow bed is the one in question. It’s 4x 8 but 4 inches deep. I’m running it continuous flood to drain now bell syphon (worries it’s to shallow to do) then it goes to a small 40 gallon res from there it is then pumped back up to a grow tray on top of the ibc tote before draining back to the ibc tote. The total plants is now 4 cucumber, 4 pepper , 38ish lettuce. my main question is should I change my grow bed to a deeper one (7 inch) with a bell siphon or should I just add a filter to my existing system, (or is the need for a filter outweighed by my plant ammount)
  13. Ok so I have a question then. If I’m using a 4.7 inch continuous flow grow bed 8 foot by 4 foot powered by an ibc tank with 40 tilapia. Should I run a filter separate as well. I’m using hydro stone (not the floating kind) but is still very light. On top of the ibc tote is another 3foot by 3 foot grow bed. The combined plants is 3 pepper, 3 cucumber and 38 lettuce plants.
  14. Hi Siddhu243 Welcome to APNHQ. Most probably you hurt the plant root, when transplanting it. You should grow the seeds in a small rockwool cube and transplant that into a larger one, or grow in coco coir, leca etc. Point is coriander (roots) does not like to be moved, so you move it with what ever media you seeded it in. cheers
  15. Dear Luke I have just acquired a 10 acre land for aquaponics. It has a spring stream running through it. Can I use the stream for th e aquaponic system by pumping into the system and recycling it back into the stream instead of fish tanks? There are fish in the stream but I intend to expand it to a 2acre pond with more fish added. I need your expertise on this Please. Thanks
  16. hi, i have planted a well developed corriander plant with roots in my aquarium aquaponics directly immersed the roots in the water. for the first two to three days the new leaves were sprouted but after four days the plant was getting dried out. i dont know what was happening to the plant . anybody please help me find out what is the problem.
  17. Thanks for the reply. I’m surprised to hear that red wrigglers do not eat solids - my understanding was that in compost heaps and worm bins they are voracious consumers of dead organic material. Is it a different story in media beds for some reason? I do filter the intake, but even so the roots will eventually fill up the gaps. Anyhow, good to know you think the worms will make it down there. Thanks again!
  18. Worms dont eat the solids. They eat the bacteria that breaks down the solids. Dont expect the worms to clear up your issue with the water flow. Seems you should be filtering the water before it goes in . To answer your question .... yes they'll work their way down, but if there is an anaerobic zone in your bed the worms wont survive.
  19. Hi folks, TL;DR: Will red wigglers be able to fit between small clay pebbles in a growbed? If not, what will? I have a very small DIY aquaponics media bed on top of my very small aquarium. My media bed is filled with 4mm-16mm clay pebbles. They're firmly held down by a sort of mesh, as otherwise they float (oops, live and learn). These are the pebbles: https://www.amazon.com/gp/product/B00CJIAGY6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The spaces between the pebbles are slowly but surely filling up with roots and bits of solid matter, and water flow is starting to decrease a bit. I think I'd like to add some worms to do some solids breakdown. Red wigglers (Eisenia Foetida) are the species of worm everyone recommends for this job, but I'm a bit skeptical that they will actually be able to fit between the pebbles. Anyone have experience with this who could advise me? Will the red wigglers be able to squeeze in there? If not, is there another type of worm that would be more suitable? Thank you! -Brian PS: I apologize if I've violated any guidelines - this is my first post.
  20. Thanks! I was experiencing an ammonia spike, which was because I was way overfeeding my fish. Stupid mistake - I misunderstood how much they needed, and I was confused because it took a while for the overfeeding to result in the spike, so it coincided with the installation of my aquaponic media bed. Now it's going great! I've been harvesting basil and lettuce from my grow bed regularly, the water is clean, and my fish are healthy.
  21. Interesting little information tidbit on mealworms. https://news.stanford.edu/2019/12/19/mealworms-provide-plastic-solution/
  22. I’m sorry, forgot to mention that I’m located in Qld. Thanks again.
  23. Hi everyone! I have joined this fantastic forum and already running my Aquaponic system. I’m also very interested in starting a mealworm farm, but don’t know where to buy a starter kit from. Can anyone help with such information, please? Many thanks! Rodrigo.
  24. Hi CrazyBasenjiLady and welcome to Aquaponics Nation. I look forward to watching your new project. Cheers.
  25. My Grandson and I have been planning to transform a koi pond into an aquaponics system since January 2020. The pond is in an atrium--inside the house, but in its own room that is only open to the outside by an opening in the roof. There is a pothos plant in the pond and I need to know if I it is safe in an edible environment. The koi enjoyed the plant. We have lots of questions. I've gardened for over 40 years, but not in the heat of S. TX. That's why we decided to move into the atrium. All backyard gardening efforts have failed due to the heat. I just couldn't keep up enough moisture in the plants. The atrium provides some shade along with the pond. I plan to add outdoor fans to keep the temperature down. We look forward to learning a lot and hopefully enjoying the fruits of our labors. Thank you in advance for sharing your wisdom.
  26. I just wanted to make sure Philodendron is safe in the same system with edibles. I have an existing koi pond (no koi at the moment) that has Philodendron in it. I've started tomatoes, cantaloupe, chives and marigold in containers. My Grandson and I are planning to build the system over the next few weeks as a way to make learning gardening fun for him. If Philodendron doesn't mix with edibles, I can pull it out and drain the pond.
  27. how to take out the solid wastw from a rectangular tank??? can a pump do it or should we do it manually????
