  1. 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
  2. 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.
  3. 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.

    Hi Praetor360 and welcome, You've come to the right place to learn. Enjoy the journey. Cheers.
  5. Hi OP,

    I was just looking through the forum and see you popped in.

    Have you been well?

    What are you up to now days?

    I bought a new place about 18 months ago and at the moment and all things being equal this is where I plan to stay until I die. 

    Adjusting to very small back and front yards takes a bit of getting used to. but living close to everything and having all this fair city has to offer outweighs all of that by a long way.

    Just thought I'd say hi and take care.


  6. Ha, ha, ha, ha.....Very clever Ande... Well the expected top was actually 31C for Sunday not the 39C top which my app told me. A drop of 9C in 1 day, which is not uncommon so, you must be getting some nice warmth coming through now Cheers.
  7. That's a beautiful place over there Ande, and I love the flowers. The temp reached a max of 40 C here yesterday. It would of been very hot in those V8's yesterday, flying around the 250 km's of the street circuit. Went into town last night and were people everywhere! Another 250 km's to race today with some relief from the heat expected We're heading for an estimated top of 39 C today. So let's pump some more temp into that tube for you.
  8. Hi Ande, Not sure if Sam got any actually...It's been freeeeeeeezing over there. The tube must be clogged up!!! No matter how much I pump into it, nothing seems to be coming out your end!!! We're heading for another week of high 30's and low 40's. Very hot for the V8 Super cars racing this weekend. Mad March in Adelaide. Cheers.
  9. How's the tube working Ande? I've been pumping some degrees C over to you. We're heading for a top of 32C today with a minimum of 19C over night...Loving it!. Cheers.
  10. The tube is finally working lol. With that weather now Ande, You'll need to borrow one of my fleet.Take your pick Cheers.
  11. Hi Ande, It doesn't look like your boats are going to go far ATM We're heading for a nice 35 C here today... I'll have another go at sending you that 15 C today. You sure could do with it. Cheers.
  12. WOW Ande, That looks really, really cold over there. The temp has dropped into the 30's here now and climbing Theyreckon it'll get to around 39 C again later this week. Looks like that 15 degrees is heading your way mate....:) I did send it a while ago to you, it must of got caught up :). Cheers.
  13. Welcome to APN Bagyaarun, Plenty of info here, You may also like to check out Ravnis indoor system. Cheers.
  14. Hi everyone, For those who don't know about our fair city, Adelaide is the capital of South Australia.The population is a modest 1.3 million plus, with a total land area of over 3,200 square kilometres for the greater metropolitan area. Below are some images.'s_updated_montage.jpg We have mild winters and hot summers. Today has been the hottest day ever recorded in Adelaide, reaching a top temperature of 46.2 C (115.16 F) Cheers.
  15. Hi Willroy, When I first started off with aquaponics, forums were the go...I was a very active member of 3 forums. there were many active participants and many more "sleepers". I feel the biggest contributor to forums being inactive along with consistent changes in personal living and lives is the advent of other social media platforms becoming far more popular.In general, the new school people just like to look at pictures maybe post a couple of short comments maybe post a picture of their own and move on to the next thread. In these type of forums we are far more involved than that and because of that we are far more technical and get the most benefit IMO. As an example, one of my businesses are listed on twitter but I just don't get how that works yet others love it. Pintrest is interesting for pics and maybe some particular Thai recipes but it doesn't give you the experience of cooking, the whys where and how does this work. I enjoy YouTube, but do not understand the monetization side of it, yet my son completely understands it and is right into it. So yeah,I agree,these forums do display a lot less "visual" activity then in days gone by. Sometimes you do find that people do move to other things and some do actually come back and become active again. As for me, my life has changed since I first started and I have become far, far more busy with life and actually struggle to find time to be on all the forums I used to be involved with and certainly to the extent I used to be and even at times struggle here but I still enjoy forums for their technical aspect better. That's my opinion anyway. Cheers.
