nexus are best
At the BKKS show today we went into the evolution aqua tent and yep, its official, from the horses mouth , nexus are best.
When i asked if they are developing a drum to fit inside or go with the nexus , because the general consensus seems to be that they are falling behind.
His reply went something like this …"nexus are better for a koi pond, than drums and bio chambers because drums take too much out of the water, and a pond and the k1, actually need all those fines that a nexus lets through to flourish, the filter bugs need all the fines to feed on, so effectively drum filters starve your bio chambers and makes them less effective than the nexus, oh and we have been doing this for 15 years, so we know what we are talking about.!"
At which point we parted

I wondered when you’d add this
His reaction (& yours!) was priceless, I had to walk away as I was grinning so much

Don’t go saying that on the EA Facebook Group or you’ll get barred like i did - with a very odd response on Messenger from a certain Salesperson, no doubt the same person you spoke to.
I did the same thing in Arcen last year and to be fair they do now have some pretty clear ‘scientific’ findings around the Nexus and denitrification (K1) in general (Nishikigoi Yearbook # 5).

Well,maybe the Nexus is a good filter but i had an Eazypod & then a 220 which i have replaced with an Oase Proficlear drum.Two reasons for this,the main one that as i get older,it gets more difficuly to operate the valves & it never cleared the fines even though EA state that they do.The other reason is that cleaning it in the depths of winter does`nt appeal to me at all.As for the drum constantly removing water,i have found that the 220 held a lot of water so after two boils averaging twice a week,the drum uses no more water that i have noticed & the water clarity is brilliant.

as a nexus owner i have to stick up for them,in a way,i have to agree that it is a good filter,its certainly better than the sieve and bead i had before,as for fines,yes the nexus has never been good with fines,but are fines bad for a pond,or is it just us that wants gin clear water,is gin clear that good for the koi,myself ive never been bothered with gin clear water,as long as my koi are happy,and think of it this way,how many filters are still going after so many years apart from the bay filters and not really had to change things ,just my opinion on it,andi

Good job you're not bothered about clear water if you have a Nexus lol. EA full of poop I reckon. Load of rubbish.

I’ve got a nexus 220 myself and yes ok it does alright in terms of bio, but I was never happy with the way it handled finer particles - you could physically see them going through the easy etc and back out into the pond and whilst it may not actually be “that bad” for the fish, it looks unsightly and can spoil the effect of looking at your koi as those same fines really show up against lighter coloured fish!
I fitted my nexus with a Draco drop in drum and it’s so much better at handling the fines now, and it has the added advantage of making the filter “almost” maintenance free, and it’s got to better for the fish as there isn’t an ever increasing amount of muck n sat in the vortex section waiting for you to flush it away.
I know when I went away for two weeks a few years back (before I got the Draco fitted!) I had to cease feeding the fish for those two weeks to try and reduce the chances of the filter clogging up, and there not being a mass off sat in it when I got back!
Now though (ok - barring some unforeseen thing like the water getting shut off or the power going out), I’d be more than happy to leave the feeder going and bog off on my jollies for a week or two and be pretty confident that everything would be ok when I got back.
I think though the main point of all this was the reps claim that the nexus filters are better than a drum and bio chamber or combi bio unit (what ever way you want to spin it!), and I really don’t agree with that for the reasons stated above, and there supposed “revolution” with them adding a self cleaning kit , well sorry but it’s a flipping joke, a bloke in a shed can (& did) do/come up with better, and I suspect for a hell of a lot less time and monetary investment too!!
Would I recommend a nexus filter now though, having had experience of them? - maybe if the budget of the person was “that tight”, but if they could afford better - no way as there are alternatives out there that are leagues ahead now, and ok, also stuff out there that gets touted as being more than capable - but in reality is waaaaaaaaay worse too!!

I think the simple way to answe this is.how many had a nexus before getting a drum.and if there where no drums.i bet youd still have your nexus lol

My first filter was a Nexus. Never again. And what's with all the de-nitrification claims. Don't believe all you read. I don't believe it for a second.

If they’re were no better alternatives to a nexus (if it was the pinnacle of filtration), then yes We’d all be rocking them, but it isn’t and it’s far from it too, I’d argue that a well sized bead filter will do a better job both in terms of bio and actual mechanical filtration, and by that I mean a proper bead filter not those that are filled with k1 micro. Proper ones such as the advantage filters from Sacramento koi.

Muttley - have you read the article in Nishikigoi Yearbook #5?
Nothing to do with EA, a number of Dutch scientists looked at a Nexus, a Drum, a Bead & a Shower - all on identical ponds and measured denitrification - the Nexus came out of top by a fairly wide margin.
I’m not on side with EA; I’ve had an EasyPod, then a Nexus 220 and struggled like everyone else with fines, I was purely trying to add a bit of balance to the topic.
Personally after my conversation on the subject I’ll never buy anything from EA again, and I certainly don’t want anything to do with a certain Salesperson.

Out of interest, how was this test done?
Surely it wasn’t a test with a nexus vs a standalone drum (no added bio) vs just a pump fed shower vs a bead, or was it!??
Me personally I have the nexus with Draco & a shower as well on the understanding that plastic media is good with handling the ammonia bacteria, and ceramic media’s are better with the nitrites/nitrates!?

nexus are best
Yep, that is pretty much how it was BH, as you say it wasn’t a Combi Drum, just a stand-alone.
Basically EA posted the article I’m alluding to on the Facebook Group recently - I replied stating I’d happily put my Profi Combi up against a Nexus in terms of water clarity, TDS and any other ‘measurement’ they wanted to ‘compare.’ (I’m running a TDS of around 200 with my Combi; my Nexus was never below 375/400; cue all the Nexus owners with a better TDS to pipe up!!)
They really didn’t like that (fair enough) and proceeded to ban me from the group (said Salesman) then sending me a message that ‘I was a Troll and to say hello to Dean...’
Does anyone actually know the history here; I think this is ‘Deano’ who used to frequent the old Koi Mag Forum, there is obviously some bad blood, but to send me that given I don’t even know Dean, just plain odd - does he really think this person is somehow corrupting other members of the Forum to say nasty things about EA?
I simply emailed EA’s Executive Sales Director basically saying ‘WTF’ and got a rather grovelling apology from said Salesman (I reiterated his suggestion to publicly put the two filters head to head and he refused point blank).
EA and as we know do not take criticism we’ll, if at all.
My point was I’d spent good money on their products for them to only really work ‘fairly well’ and as David started the Thread with the comment ‘why haven’t you bought a drum out, surely your missing a trick/market share.’ That just falls on deaf ears because EA’s stoic view is that the ‘Nexus outperforms anything else.’
We all know the filters work, but using the term ‘outperforms’ is what pisses me off - yes it may outperform a Bead or a Shower, but a Drum/Moving Bed or Combidrum is surely a fallacy.

Surely it was a drum + a Bakki shower though, and not just a drum on its own, a bakki shower on its own if you get me, if it was then that makes NO sense as a drum is purely meant for mechanical filtration isn’t it, just as I’d imagine a bakki shower is only really meant as biological filtration isn’t it!?
If it was a nexus vs Drum + shower or a bead filter then that makes more sense, if it was the former and it was JUST a drum, JUST a shower etc then that’s a really dumb comparison to make in my eyes!
Bet they’d (ea) never do a comparison of a nexus vs a combi bio unit (that carried the same amount of media for fairness)

That was also why I asked EA if they were involved in the Study, I.e. was it skewed towards the Nexus (running a Nexus against a Drum, Shower, etc.) No involvement was the categoric answer.
I’ll check the article tonight but I’m pretty sure it was just a Nexus vs. the other methods of denitrification - the article states ‘Rotating biological filter’ hence me querying it in the first place.
I’m surprised no one else has seen the article, given how we all love a copy of Nishikigoi Yearbook (or is that just me!)
They’d never do that test, because we all know what the results would be, as you say.

I’ll be interested to see what’s what on this if you check and confirm in the book what was actually done, because to me it’s sounds like a skewed test!!

I detailed the name of the Paper (Study) and the table with the denitrification figures in another Thread, called ‘EA’s OC-2 Media.’
Not sure how I link that Thread to this using Tapatalk...

what are they classing as “rotating biological filter”!?!?
That doesn’t immediately translate as being a drum filter to me as there’s no real bio in a standalone drum filter is there!
Sand filter - fair enough, can’t imagine they’d be much use anyway!
Trickle tower, ok but how do they compare in terms of “supposed” load they can handle when stocked with media vs the nexus!?
