Rob Bob's Backyard Farming & Aquaponics: Thanks for watching folks & don't forget to click the subscribe button if you enjoyed the video. 🐟🐟
Share the clip around with family & friends if you think they'll enjoy it too. 👍
Cheers all & have a top one. 😊

Jeremy Young: Reapplication idea, we have tool vats with a stainless pipe and pinholes in it zigzaging a cross the the bottom of the vats. We hook compressed air up to this and open the valve to agitate the vats.

Pipe has standoffs and a grate overtop.

This might help cleaning your beds become more effective and painless.

Jay Tee: ...

Greg Hintz: Would worms in your system help keep the solids down?

JaylewAF11: Hey Rob, awesome videos! I have small system (8 sq ft bed & 50 gal fish tank) and your videos have made look into upgrade to a system like your IBC chop and flip. Have you found a way to design the grow bed so you don't get all that solids build up? Or a solid waste filter that doesn't take a lot of space? I've seen your radial flow filters but I'm afraid I won't have room for it. Did that bed have worms in it?

Jim Greenwood: Hi Rob, Thanks for showing me how to remove solids from grow beds. Made a water/air spear attached to a compressor and a water hose, flood the bed, bypass the sump, plunge it into the river pebbles and it lifts the solids to the surface. Have done 2 grow beds with 4 to do. I have used a pitch fork, extra worms, digging and water blasting and using the air/water spear is the far and away the best. Thanks again. Jim

Christopher Carney: Have you considered having rows of tubing with holes on the bottom that blast air, like one of those solar aerators 24/7?

Matthew Young: hi Rob, thanks for thd ongoing videos. would earthworms help in this case to consume the solids? Not sure if they'd travel tobthe very bottom where its waterlogged often.. does your bed drain completely?

wajdi wajdi: thank you from Ermont near Paris. good thing with u is you re showing also the problems and how to fix them. Not only the happy face of aquaponic

joe smith: G'day ,when I made my gb's I cut them from the sides instead of top or bottom ,you get two beds from each ibc and they have nice flat bottoms .You then use tank fittings for the drain.You then cut the ibc cage to the height you want ,incorporating the base ,you then use the leftover top section of cage for a stand, ie the base sits on top of the top,you may have to cut the corners of the cage to open it outwards to allow the gb to fit.You can also jump up and down in the centre of the base to form a sloping bottom to your gb's.I also noticed that you don't have nearly enough holes in your media guard to allow fast draining which I found made the auto siphons play up a lot , as in they would not break cleanly.I found that angle grinding as many slots as you can, vertically is best.With this setup I have found they stay quite clean as there are no low spots.I have learnt a few things from you and I hope this info is of some use ,Cheers mate.

Frank Kopke: Would it be plausible to incorporate an air line/s UNDER the chosen medium before filling a grow bed? This may allow for air to be pumped in at the lowest levels without disturbing the most of the medium or any of the plants and still make it possible for the water to be flowed throughout. I am unsure as to whether a air compressor would help or hinder this as I think there could be too much pressure in such a system. Ideas?

Eco-Hub Mexico: Hi Rob.
Thanks for all your great videos!
I have a question regarding grow media. I live in a desert area in Mexico. In summer it tops 40C. I understand expanded clay pebbles heat up very easily. I was thinking of using these but putting 4" or so of suitable natural stones as a top layer to help protect the clay pebbles from the heat.  Would this help or is there a better way?
Thanks in advance!

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

xxxsavagexxx sports: Also will be great if you tell where did you get covered material for you greenhouse. Thank you in advance.

xxxsavagexxx sports: May be it is really because of sun. But fishes are ok.

xxxsavagexxx sports: 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 your greenhouse.

xxxsavagexxx sports: 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.

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.

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 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 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 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 up.

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!

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?
