If you look at the video (2min 45sec) you can see that the standpipe is simply 100mm black soil pipe. The inner section is the same, just cut apart. The whole thing is removeable because it has a ringseal at the lower end. Not much more to say of show really.

@@ukzerocomThanks!

Direct fro the quarry. Had to have a full lorry load, so only valid if you need a lot!

Thank you for the kind comments.

First two as you surmised. As to the proportion passing through the moving bed it's hard to say, but in my current system the main flow is under the moving bed (which is contained by perforated mesh) and so the mixing here will only be due to turbulence in the bed itself - so most goes straight to the air lift and anoxic. NO3 is not zero, but averages at about 10ppm. Hope this helps. PS I don't feed intensively as rapid growth not a priority.

@ukzerocom Thank you. Not being able to find the 30x30 baskets cited in the articles, mine are 28x28 and perhaps I should recycle them into 40x40s like you have, as essentially my original system had everything you have but with lots more baskets, as I have two independant small drums, two air lifts and two anoxic ponds with 50+ in each, so one side could fail and the other be enough to run the pond but I never got past 200g feeding per day. I did worry that the air lift before the anoxics rather than after them was the problem but you disprove that, too. All great information from you, thank you and the search for anoxic success continues!

Please might I ask for another little bit of information? I'm going to re-pot my small baskets into large 40cm ones. Do you recall how much Aquabasis Plus, you put in each core of your baskets? 200g is suggested by Mr. M Sanke but I wondered if you did something else.

I have spent some time at the factory with the designers and I don't believe the price hikes are due to "profiteering", but more influenced by a considerable increase in cost of materials and skilled labour. However, it is true that they are now even more expensive. Unfortunately it isn't simply a matter of buying from a competitor - there is nothing out there that comes close (the Tabbert Cellini is both over £100k and too long for UK towing law - unless you tow with a lorry). Please note that the latest Inos now on sale has some minor changes compared to the one in these videos. Don't forget the open day at the Inos factory next month. On a more positive note we now have a FB group made up of owners and prospective owners where you will be able to check out what others think (and see what other mods I've let loose on our 'van!). You'd be welcome to join.

Thanks for the kind words. All the mods shown (and one or two added since and at least one more siginificant mod to come) have been designed and carried out by me. No manufacturing background, just an incurable case of chronic DIYitis and a rather obsessive nature in terms of fit and finish. If you are interested in the Inos we have started a Facebook group for both owners and prospective owners.

Thanks for the reply. Well that work looks very professional, I am very impressed. I am a complete duffer as far as DIY goes, but I did site a new plastic clip (that keeps the door ajar on our Dometic caravan fridge!) yesterday, which about my limit! We did look at an Inos at one stage but it is out of our price range. Thanks again for an interesting review.

Thank you for the kind words.

No. The Inos body construction is much thicker and heavier. The Fifth Wheel Company in N Wales who make the Inos have been making them since at least 2011 as far as I know. I believe the company you are thinking of is Eterniti - who made the Genesis. They were a great idea, but had various issues I am told and I have seen more than one with delaminating bodies. A fair proportion of folks on site who strike up a conversation start with something along the lines of "I see you have a slideout, didn't that company go bust?"....

Thank you for the kind words. Coachman do make some lovely caravans.

Thank you for the kind words.

Thanks for the kind words.

Thanks for the kind words.

Thanks for the kind words. I believe the Inos has been produced without a break for over ten years. It is sometimes confused with the Genesis by Eterniti, which also had a slideout. Eterniti ceased trading some years ago. If you are considering an Inos we have just started an Inos Caravan Owners group on Facebook. More details of my caravan are being published on my Inos Caravan web page (still adding to it) which can be found here: www.ukzero.com/Inos.htm

Yes your correct the Genesis, I must admit I wasn’t a fan of the Inos front elevation the single functional window spoiling the look, however a your simple black graphics transforms the front aspect, perhaps Inos will adopt. Unfortunately I now remember it was the weight and price I felt we couldn’t stretch to, we ended up with the Lusso 2 which had to suffice.

Not sure if the company can just copy my designs without permission? Anyway - a Lusso 2 is VERY luxurious inside and so you aren't exactly slumming it :-) Happy touring!

Wow, that’s one very expensive caravan. Still, if you want quality you usually end up paying for it. Wishing you health to tow!

@@ukzerocom both parts 1& 2 were so interesting! Ive sent them to a friend , he bought a lovely Bailey Unicorn Pamplona twin axle new and added E&P but also many other improvements . We were very lucky to be able to buy it from him but to our great regret we sold it some months later to buy a Motorhome ( big mistake). We really miss it it was very individual. Your Inos is just stunning! The Ultimate caravan and reminds us of a beautiful yacht inside .

@@vicdunni I have come across an increasing number of motorhomers who are moving to caravans. At one time the trend appeared to mostly be the other way round.

@@ukzerocom yes we tried a MH but a caravan is better in many ways. You have a car to use on holiday ( i know you can tow one behind a MH but defeats the object) also no MOT , no engine to service etc . We did prefer the journey in the MH though 👍

Averages: NH3/NO2=0, NO3=<5ppm, pH=7.5-8.0, KH=4-6.

@@ukzerocom So the anoxic filtration does work very well then. I have been planning a pond which I hope to put in next summer, and very much want to do anoxic filtration its nice to see videos confirming that it works well. I like how you have the anoxic baskets hidden in the pump house, my former thought was to make sort of an upper and a lower pond with the baskets at the top a waterfall coming out of that and feeding the main pond...but I dunno I'll have to think on keeping them totally hidden as you have here.

Thanks. Over a year since it was upgraded and proving well worth the effort.

Nitrates have reduced from up to 80ppm (and occasionally higher) down to less than 10ppm. I would not expect nitrate levels to reach zero because the system is a "variable hybrid" design and so retains a variable degree of regular Nitrogen Cycle NH3 to NO2 to NO3. Even with the bypass wide open there is still some deliberate "just in case" residual "normal" activity in the moving bed media and of course the rest of the pond system's surface biofilm. I didn't have the courage to completely switch to 100% anoxic with a fully stocked pond and no quarantine/backup.

@@ukzerocom what did you use for your anoxic filter? Catnip?

I used Kittyfriend Pink cat litter.

Sorry - missed these comments. Being cognitively challenged I don't really understand them I'm afraid.

@@ukzerocom What is the size of your BCB?

@@rockfella27 Ah, with you now. Yes regular sized baskets as you surmised. There are 15 of them for my 7 fish (24"-28"+).

@@ukzerocom 2 for one adult wow. Nice.

Thanks for the kind comments. I will do a second shorter video which will focus on the pond. Given everything else we have going on this will now be next Spring when the pond will be nearly three years old.

Thanks. Especially given the anoxic element 👍

Sorry, just seen this. NO3 is running consistently between 1ppm (mg/l) and approx 4ppm. To put this into context, this time last year without the Anoxic it was hovering around the 50ppm level. My water changing is purely controlled by level drop and not by constant trickle-in, so is much less than is often the case for Koi ponds and explains the highish pre-Anoxic NO3 level at this time in the season. Hope this is of use.

@@ukzerocom That's is very good indeed.1ppm-4ppm.I am very impressed. Dr. Kevin Novak should be elated. He is giving greater insights into the BCBs [biocenosis clarification baskets] currently. Electrical/ionic charge, difussion, and convection[thermodynamics] forces in the BCBs.

1-4!!! Woah! Nice! Thanks for sharing!!!! Dr. Novak must be elated!

There is still the "back up" conventional moving bed filter running in my system. Although only a small part of the flow is now through this moving bed I have to assume it is still functioning at low level. With that in mind my Nitrate levels are not zero, but remain low (~5ppm) despite Summer feeding and much less than usual water change rate. Ammonia and Nitrite have remained at zero throughout the transition to more Anoxic operation (apart from during KMnO4 treatments). There are people who have gone 100% Anoxic who may be in a better position to comment.

That’s very encouraging, just one final question, what did you use for Laterite?

i am more interested how long cat litter last

I used special pond paint on top of a cement based tanking compound. To be honest it took an age to cure and is not very robust. If there is a next time I will go back to proper GRP as I have used in the past. I would never use non-reinforced flow coat as it will always crack and lift in time.
