  3. Hello all, It's been awhile since I've posted, been a cold relentless winter and spring here in ontario, but the greenhouse is still going well. I have a 12x16 greenhouse with one warm water system (approx 400 gallons of tanks, 30 ish niles, 20 ish blues and seperate aquariums linked in with minnows and other fish) and am about to finish a cold water system no heat, on other side of greenhouse 450 gallon sump buried, 2 mechanical filter barrels and a 220 gal fish tank. In cold water system I hope to put perch or rainbows in. So I'm waiting a few more says for the silicone to cure around viewing window in cold water system. I tried a couple times to put window in bit failed. Determined I made this 'jig' and it went ok- i think- i will know this weekend when I test it. I'm trying to upload pictures from my phone. If it doesn't work right now I will download from phone to computer. I thought I'd post the pictures for people interested in installing windows and share my experience. Cheers

  5. Hi amarnanibharat, If DWC is the way you want to go then properly designed filtration is the key IMO. I'd connect each one of your rows up by having a drain in each tub going to a single drain then running the single drain to the end of the row then a single drain for each row draining to a media bed filter at a minimum, then run the media bed filter to the fish tank. If you can or will add more or better filtration then your system will have a higher chance of success One other question. How do you plan on growing your plants in your rafts? Cheers

  7. Hi Farbulous...great to hear from you again. 1. Since iAVS uses a sand bed as a biofilter, do folks using this type of system, (ideally if you're using it indoors,) find that there is much odor from the decomposing fish waste? There's little information on indoor iAVs's, so it's hard to give a definitive answer. When you talk about 'indoors'...how indoors do you mean? 2. Do people use worms in their sand beds to help break down the fish waste? What are your thoughts about having worms in the sand bed? No. There's no need. iAVs relies on a decomposing detritus layer on the surface of the sand...in the furrows. Worms would only drag the decomposing fish wastes into the sand - not what we want. 3. Can the design of the system be modified to incorporate other modules such as NFT troughs, DWC rafts, (non-sand) media beds? I would assume that any of these would be placed after the sand bed for the purpose of filtration. If one or more of these modules were part of the overall design, would that necessitate a sump tank? If you had a Ferrari, would you want to put Nissan badges on it? In any case, you would only know the extent to which the hybrid works if you had a standard iAVs against which to measure it. Start off with an iAVs and then experiment from there. I see you've registered over on my HMFL forum. If you want the latest information on iAVs...go HERE. Gary
  8. All responses are much appreciated! Thanks everyone.
  9. Hi So now he is back in the limelight cheers
  10. Hi BD Here https://www.havemoreforless.com/forum/micro-farming-microponics/the-integrated-aqua-vegeculture-system-iavs/1458-question-one-or-more-of-many#post1458 cheers
  11. Hi Folks, Some time ago I asked the question of weather iAVs produces any odours the question was recently asked again so I did a quick search and could not find my question or answers to it. To save us both some time, could someone please reanswer my question, plus if there are any different answers people have now we are sometime further on, could you please post them here. Cheers.
  12. Hi, Farbulous A couple of thoughts on your questions. 1. Since iAVS uses a sand bed as a biofilter, do folks using this type of system, (ideally if y ou're using it indoors,) find that there is much odor from the decomposing fish waste? I asked this question some time back and the answer was no smell, the answer is somewhere in this forum ATM my time is limited but if you were to search for subject matter like iAVs questions or the like,I think either Gary or Mark did answer that one for me. 2. Do people use worms in their sand beds to help break down the fish waste? What are your thoughts about having worms in the sand bed? Whilst I can't see anything wrong with this, I don't use them even in a gravel bed biofilter. I tried in the early days but found they disappeared. When growing worms separately, I found 22C or 23 C is the ideal temp for worms to be working at their best, 3. Can the design of the system be modified to incorporate other modules such as NFT troughs, DWC rafts, (non-sand) media beds? I would assume that any of these would be placed after the sand bed for the purpose of filtration. If one or more of these modules were part of the overall design, would that necessitate a sump tank? I can't see anything wrong with adding NFC, DWC or any other forms of growing systems to your original and yes after the sand biofilter. The sump question would depend on your design but I would think to add a sump would be the easiest. Remember adding anything to the iAVs sand filter will complicate things more and that is veering away from Marks idea of keeping the system as simple as possible. But give it a try and let's know how you go. Cheers.
  13. Hi Farbulous Welcome back The forum have been very quiet for some time, but hopefully @Aufin @GaryD @Ravnis will chime in and give some insights on your IAVS Q's If not, you could try to post the same Q's on Garys "new" forum https://www.havemoreforless.com cheers
  14. Welcome aboard!
  15. Hello fellows. It's been a few years since I've posted on this site, but I am now possibly in a position to build and install an AP system at my current workplace. We operate a moderately sized indoor greenhouse (concrete slab floor). There are so many options out there in terms of systems and components, but I've been looking into AP for many years, and have read these forums many times. The consensus these days seems to be iAVS as the go-to system for ease of design and operation. I can totally get down with that. We want something that is not too large, but can be potentially expanded upon in the future. At first, we will probably be using non-food fish such as goldfish just to test it out and get a feel for regular maintenance and operation. I'm sure I will have more questions over time, but for the moment, here are the two that have been top of mind: 1. Since iAVS uses a sand bed as a biofilter, do folks using this type of system, (ideally if you're using it indoors,) find that there is much odor from the decomposing fish waste? 2. Do people use worms in their sand beds to help break down the fish waste? What are your thoughts about having worms in the sand bed? 3. Can the design of the system be modified to incorporate other modules such as NFT troughs, DWC rafts, (non-sand) media beds? I would assume that any of these would be placed after the sand bed for the purpose of filtration. If one or more of these modules were part of the overall design, would that necessitate a sump tank? Thanks in advance!
  16. Hi am Wesley looking at starting a small scale system any advice
  17. Raining outside, nothing exciting to do, so, taking a spin down memory lane. Wondering how things are coming along in Sacramento.
  18. Any progress update on this project?
  19. Wondering how your AP setup is coming along. ...... if you're still going forward and what style AP you've decided to build.
  20. Thanks ande, was a ruff job in the heat of Thailand but at the end it was worth every Thai Baht spent. My wife called me today and gave me an update. This new system is not that labor intensive anymore, the system is working well balanced and the new 'baby station' gets already stocked with berried females who start producing confirming that we did all right. One negative issue: The clay pebbles we bought are fully soaked but will not sink and create a small void between the river gravel and clay pebbles. She got more river gravel and reduced the layer of clay pebbles to about 3 inches which stops them slewing around.
  21. Hi Will Nice update Thanks for sharing cheers
  22. Hello all, after we had collected with our 1st backyard system (and also many info from members here and other forums) all oops, mistakes, do's and don't dos, I spent these 2 1/2 month off-time to overhaul and change the entire system as already pre-announced. The test system is completed today with the last task, a so by my wife called 'baby station' 1. The continuously overheating pipes which should simulate for my wife to learn the idea of deep-water grow beds, have been exchanged to some bada** backyard deep water grow beds and two ebb flood gravel beds. Have mercy with the height on frames. In my commercial system I will move a lot of dirt to reach the desired levels but in our backyard is this not make-able without pushing the wall into neighbor's garden. 2. the Filters have a bigger size and a sump tank was added. The pump has all capacity from 12000 L (actual size) to 48000 L adjustable by remote control. Also we have inserted 2 stainless steel filter buckets 500 micron that catches almost every dust and poop particle. The poop is pure Gold and our entire Village is just turning into a jungle. We give every week an around 5 Kg bag to our neighbors and all confirm that the cray and tilapia poop mix is the best all-round fertilizer they ever had hands on. 3. Six Breeding stock buckets 400 L, four 800 L grow out Tanks, eight containers as baby station and off cause our two grow beds each 5000 ltr is now considered as a home for our red claw crayfish stock (about 2500 ea) plus three ibc cubes each 1000 ltr for our tilapia provide the fertilizer. The 'expoxy liner' over smart boards approved as most useful, very strong and durable. After completion of each layer I was flying 50cm above the ground and we decided later to give this job in some local hands. The 'baby station' 8 containers, simple and efficient. Thumb up from my wife. 6 breeding stock tanks (5-8 females and one male) and the grow out tanks below. A (not suitable for Offshore working) Davit Crane helps my wife every morning to change the filter buckets. And there is no better place for me and my wife sitting on the bench and listening the sounds of splashing water, slurping Bell siphons and watching the crayfishes searching for food. Rafts, funny feeder funnel and the first vitamins on the grow. A backyard packed with ideas. Btw, we got heaps of offers for floating rafts worldwide with prizes that went through the roof. Then we found a supplier just 120 Km away who offered us 50 holes and 15 holes rafts for 120 Thai baht a go which is equal to 2.50 EUR a piece. Hard foam plates with pre-drilled holes and air pockets underneath = money well spent. Job is calling, in two days I have to go offshore again leaving back a happy and proud wife and a new improved system. The water test results, the growth of the first veggies and the boosted hunger of the Tilapia and Crayfish have already proven that my little wife and I are on the right path. 2 weeks ago we bought some crayfish food that was lowest quality and started floating after 1-2 hrs with the result, that ugly slime was covering the roots and root rot started. As experienced before didn't the crayfish take long and took over their duty. They clipped the bad roots out and boosted the growth of new white roots. A stunted growth could not be observed as the mud-bugs had their job well under control and gave us a lot of optimism that red claw crayfish do very well under the floating rafts. Our expectations that the Crays will going berserk on the Veggies turned the opposite and they approved that they are well educated gardeners with love for any decaying matter in roots and plants. The trap housings working best and only thing is how to feed them as at the moment. We equipped some raft holes with funnels which is ok for here but sure impossible in the commercial size grow beds we are planning for our commercial system, but that is future music for now. As I said, offshore is calling again... Cheers Will
  23. Hi, I would need to breed pairs of Nile Tilapia (one male, one female), in a recirculating water system which includes biofiltering. The fish would be raised from fingerlings and bred upon maturity. I do not intend to keep each pair for more than 1 year of age. I am wondering what would be the minimum tank dimension for each pair. Of course I could use 500L tanks but, needing at least 50 tanks, it does not seem economic. Thanks for your comments. MN
  24. Hi MnrPresident Welcome to APN/HQ cheers
  25. Managing fruit and wine grape farms for 14 years, now studying aquaponics design in order to set up commercial venture, and go it alone! Planning a test garden once we've moved to town, which is end of April.
  26. Oh dear, I forgot to include the port number. http://70.162.39.217:8080 This should work now. I couldn't see how to edit my post. O.o
