Memories of yesterday: Hi Rob, Im new to aquaponics and just completed a grow bed using clay
balls, on my first test the balls which is about 250mm deep started to
float and almost overflowed to the edge if I didn't scoop it back in, is
this normal? cheers mate
Alisher Nabiev: Hello, thank you for respond. Yes I have a tant with plastic( Cellophane)
covered on it. I would like to know what kind of material did you used for
Joshua Falcon: Hello,
I've got a few questions as I am planning to start my own auqaponic garden.
I've found a 55gal drum set up that would be great for me to start with
considering my space is limited. I will share a link bc I am looking for
opinions and was not sure where to turn.
So this "barrelponics" set up is pretty simple. But I wanted to ask about
the clay ball substrate you use and I was curious if you think it may work
in this size set up?
I have also found you of Facebook and sent a message there. Thank you.
Alisher Nabiev: Hello, my water tank is getting dirty. I bought some gold fishes and put
them to my water tank with store water in which fishes came. Is This the
reason of getting dirty? i am cleaning my water tank and in 3 days it gets
dirty again. It is kind of gets yellowish then turns greenish. I am not
sure what I am doing wrong may be it should be like that because of fish.
livefastdieyoung26: Why don't you get rid of the hydrotin ( clay pebbles ) and float all your
plants on foam? That way the water flow would be better and less gunk would
settle on the bottom?
Olen Soifer: Hence, the difference between DWC hydroponics and grow media aquaponics.
That smell is from anaerobic conditions developing down at the bottom of
the beds...like in a septic tank. Not what you want! You wouldn't grow food
in septic waste!
While you prefer not to use the actual under-gravel filter that are
sometimes used in aquariums...you might consider installing a course screen
under the media, a couple of inches up from the bottom, so the media
doesn't do down to the very bottom of the beds. Then, if you limit the
drain holes to the bottom couple of inches of the standpipe...below the
level of the media...you might find that you can get some good turbulence
in that media-less bottom part of the beds. Perhaps, considering how much
flow bell siphons can develop, that could dislodge the sludge as fast as it
builds up and carry it out to the filter so that the sludge doesn't build
Of course, the other issue could be inadequate filtering Some people don't
use filters at all...and they like to show off how clean their fish water
is. But, of course, what's happening is that they are sludging up their
grow media, turning them into the equivalent of septic tanks. Sooner or
later they'll certainly have the same issues you've experienced. The
solution is more filters. "Backyarders" don't differentiate between
settleable and suspended solids. The homemade swirl filter doesn't remove
the suspended solids...but the grow bed does! Using bag or drum filters
might be the only practical solution. I haven't seen anyone come up with a
homemade drum filter yet, but someone will sooner or later!
Alisher Nabiev: Also will be great if you tell where did you get covered material for you
greenhouse. Thank you in advance.
Alisher Nabiev: May be it is really because of sun. But fishes are ok.
bo ter berg: After watching this, my first thought was that the problem started with the
shape of the IBC's. The ones you cut the sides off may not have these
lower parts. Another option would be to level the bottom of the bed with
cement first. Very informative again, thanks :o)
Roberto carlos machado gomes: Olá Rob Bob, boa noite!
Gostaria de saber como você administra os fertilizantes nesse sistema de
cultivo hidropônico, e quais são eles?

KaleidoscopeJunkie: A siphoning gravel cleaner for aquariums should work well. It pulls all the
decay/debris with it so none can escape into your system. I prefer the
siphons that are not self priming because those has smaller openings that
trap debris. I have three types and "Aqua Culture Regular Gravel Vacuum
Cleaner" is My fave. (Some decent videos on YouTube ;-) bout using them in
Miles Komora: Thanks for the cleaning tip!
I'm only into this for less than a year so your tips are very appreciated!
Yaqub Lourens: Hi Rob. I'm looking at starting a AP here in the north of Arica.I'm just
wondering, isn't it better to but in a solid filter so that you don't need
to deal with the solids in the grow bed??
Thanks for a great video
Freddie Bagger: Maybe I am to young in this AP, but, where do you get all the water from,
the tap? or do you have some deposit ready for this change of water.
Stephen Wopershall: Sounds like a lot of work. Why not eliminate the entire problem by not
allowing the solid waste to enter the beds in the first place? Why not use
a bed of 6" vs 10"-12"?
The decreased grow bed area ( size) doesn't affect growth rate, quality or
Ack_Zombies: After watching this video I thought you might want to try a new method of
breaking up your solids. try placing a floor burnishing pad with a cone of
some sort in the middle of it, under the water outlet. This should force
the water through the pad and filter out many of the larger solids and
allow the smaller to flow through the bed.
Sorry for the long link but here's a burnish pad. There are stiffer ones
with larger gaps in the fiber ones as well.
G510Gamer: with my small aquaponics system i just take the plants out and put them in
small container then i just take out the clay pellets and it reveales the
im thinking about upgrading 10-20 small plant system to a 5 large plant 60
- 90 small plant system :D
JIM SWIERINGA: ROB do dirty grow beds interfear with bell siphons working right? Almost
all my grow beds i'm having trouble getting them to brake siphon.I have 7
ibc and 20 flow beds. Thank you for any help. great videos. Thanks Jim
tjhutch89: Have you tried introducing red wiggler worms? Works in my small systems.
stdavross666: HELLO, WHERE DO YOU GET THE FOOD GREADE ibcS FROM???
Rob Bob: Not to sure about that but will try & help.. How big is the bed in Litres
Jayendral ?? You might want to look at reducing the standpipe down a bit
depending on the size of the bed..
Mark Allen: Great Job Rob! I just finished cleaning mine out as well. I pulled all the
media and washed it off. What a mess! I like your idea with the air wand. I
think I will be storing that one in the back of the old mind. Have a great
T Webster: Hi RB, I haven't started my AQs yet. I'll be doing that in a small area in
the basement in September. I'll start with a 40 gal. fish tank and a small
grow box. Then next spring (I live in the Colorado Springs area) I will
build a green house, of sorts, outside. Your videos give very valuable and
useful information. Thank you so much. Wayne
Rob Bob: Will be cleaning out the beds once they are de stocked further just to see
what has built up.. Should be an interesting & messy exercise I think..
Thanks have a good one..
StogieFarts: Ooops, try again. I had the video settings incorrectly set to Private.
Dale Calder: Nice that nothing goes to waste solved the problem in one system and gained
a lot of organic fertilizer for the rest of the garden.
jimsta10: Hi Rob, are there any other methods that you can suggest that can bring it
down nitrites? ie. chemicals? cheers
Rob Bob: Our plants bounced ok from being traumatised with the wand so I think they
can take a bit of damage.. Good luck with the clean out..
Rob Bob: Hi Max Would love to get the link off you of the clips if you want to PM me
here on YT. That grow bed is loaded with worms but unfortunately they can
only break matter down so far.. I had to edit the footage of them out as I
get a tad long winded.. I have a clip of some we have found before if you
would like a look QeVrZwIRf6Q Worms also contribute solids to the system as
well I have found.. TBC
Rob Bob: Think the plants loved it:) Have a good one..
enticed2zeitgeist: Isn't it likely that you are simply over-feeding your fish or you have to
Larry Shier: There was also a bio digester type filter I saw that may be handy,
basically an air stone in the bottom of a bucket with a mesh over top and
small 2cm pieces of 1/2" pvc on the top and slit on one side. The small
pieces of pipe provide bio mass and banging together from the air stone
breaks the solids into smaller pieces until broken down by the bacteria.
Max Esselmont: Hi Rob, i've been doing a bit of research, and i came across a few YouTube
videos on enhancing your aquaponics setup with vermiculture. as i
understand it, the addition of worms to your grow bed should help keep your
sediments aerated, and reduce the amount of time you need to maintain your
ecosystem. cheers, ...max
Rob Bob: That's what I found so have left the others be for the moment... Hoping
they will last until the fish are out of the system & they will get a clean
Rob Bob: I know... Think I need a larger filter to take all the solids that we will
be expecting from the tanks we are thinking of adding.. Might play around
with the one we have to see how I can improve it & a conical base would
make the cleaning of them much better.. Have a good one :)
Rob Bob: It's back for the winter :D Cheers..
UncIe Bete: I made a video of pictures I made in MS Paint. : ) Sorry, I don't have a
camera. (would be nice). I made changes while drawing these. Because of
seeing problems while drawing them. Dia 1 and 2 go together. But as seen in
the picture. The pipe would probably end up too high off the bottom. Dia 3
and 4 show this fix. Running straight out the side. But then seeing that
the curved bottom might not fix it. And I have the Need for Cheap.... Dia 5
is something you could have parts lying around for.
waedvm dogdoc: Hi Rob, great videos...thanks again. I have not seen all of them yet but
working on it :) Would using worms mostly resolve some of that "muck"
Rob Bob: Hi there.. The beds have a ton of worms in them but they will still only
break down solids to a degree & still produce waste themselves.. For me it
was a huge lesson in the need for filtering the solids out before they hit
the grow beds.. I do know others don't follow this school of though but I
do now as I have seen what can happen when things go pear shaped & the
resulting nitrite spike.. The solids are not wasted & will be building a
mineraliser in the near future.. TBC
Jayendra Birchall: Bell siphon :) I've got 110mm guard and 40mm standpipe What size for bell
Rob Bob: Foi um grande trabalho e fomos muito cuidado para não deixar a água suja de
volta para o tanque de peixes .. A lã de filtro funcionar muito bem .. O
filtro de fluxo radial parece estar fazendo um ótimo trabalho em remover a
maioria dos sólidos no momento .. Obrigado e tenha um ótimo dia ..
Rob Bob: Have a few ideas how to stop the dead spots in the next grow beds or these
if I get game enough to retrofit them.. Really don't want to have to go
through the beds every 8-12 months.. Hopping the filter gets rid of most of
the solids so I don't have to do it ever again but I think I'm dreaming
Rob Bob: Sort of makes sense.. What would be getting the much into the holes, a
siphon ?? Trying to wrap my head around it.. Thanks for the help &
Rob Bob: Am hoping that the radial flow filter will pick up any finer bits that
don't get washed off as they come through.. That might also help the system
not get overloaded with too much stirred up nutrient rich particulate.. I
think that the tap water might be too harsh on the bacteria I knock it
around a bit. Do you have another tote you could settle out some water in &
wash out one beds worth of clay a day? Hope that helps out a little bit
mate & you get it sorted out soon. TBC
Rob Bob: It was one worry we had when we first looked into aquaponics Dale.. Don't
think we have actually wasted much water at all except for overflows during
the floods.. The plants do love it I think.. Have a great one Sir :)
Rob Bob: Don't think I can do a how to clip from the start without changing it as I
go John... Should probably try to think ahead more :D
Rob Bob: No problem... Thanks for watching Steve :)
Bike Man Dan: Its too bad tanks with conical shaped bottoms aren't more affordable. Would
solve the problem of solids collection
meanshoes: A wee bit of work eh Rob. Is this something that needs to happen ofter? or
do you feel it's from a specific reason. Everything looks so nice bro
specially with all the sunshine :) Brock
thehittmann1981: I wonder how hard it will be to do this with scoria :/
