I would like your opinion on rotary drum filter ( RDF) they very popular in aquaculture and ponds but not aquaponics. RDF can be expensive compared to diy and bead filters but they have come down on price and are great mechanical filters if you the combi it takes care of both mechanical and biological. They are also great because of very little maintenance.
Thks for the vídeo! I'm just starting to plan a small hydroponic set-up. I see a lot of people only using fish, but plants need more then just hydrogen. Is it better to add the rest of the minerals like filtered compust tea before the growing beds or after? Thks
Your design is not good for plant to get nutrition. Because the diagram you show on the screen: from fish thank - filtre - degassing thank and to plant ..you have filtered out all fish waste how can your plant grow without getting any nutrition from fish?
I've really enjoyed watching your videos on the New Agrarian channel. Clear, crisp, concise, clear speech and diction. Every word focussed on the topic and addresses each issue and factor in the process. { in other words, no superfluous padding and waffle } Well worth the time watching these videos on aquaponics. Thank you, PNH
Thankyou thankyou thankyou for the knowledge, I’m from indonesia and am starting to make a commercial scale aquaponics system, I have a question, how long do you recirculate the water from the fish tank to sump back to the fish tank again? Do I need to refill the clean water once in a while? If yes then how long until I need to refill all of those water system? Thankyou.
You want the total gallons of water in your system to bs recirculated about 1.5-2x per hour. That means soong a bit of math... Grow beds hold 40 gallons total in 2 beds. Total sysyem is 100 gallons. You want those grow beds to cycle every 10-15 mins for a total of roughly 4-6x per hour meaning you have recirculated 160-200 gallons over the course of an hour. As for additional water, keep in mind that this water MUST be sage for the fish while being added. It can also have an immediate impact on your ph. That being said water will be used by the plants and some loss will occur due to evaporation. Keep the system topped off as you see fit, but make sure you always have more than enough to never run your water pump dry as this will likely be the end of your pump. I have an putdoor setup in texas and in summer at temps regularly hitting 105 degrees I can sometimes end up losing 20 gals or more in a single day. I use a filter attched to my garden hose that is specifically made for koi ponds to quickly top off water. My fish dont mind a slight ph swing and my system will bring my tap water ph down to a comfortable level in a day or so without the addition of chemicals. Hope this helps. Good luck!
Loved the video! Is it possible to do a video on fish to water ratio based on daily feed input and sizing of the filters for the same?

Re: Mineralization tanks
If you're growing things that are intensive flowering or fruiting crops, you'll ideally want a mineralization tank, or some means to extract the full sum of nutrients from the fish tank (such as an in-line, dark nektar style worm bin)
Re: DWC Beds
DWC beds having suspended solids is only a net negative if:
1) your oxygenation is less than adequate
2) you lack a population of filter feeders / bottom feeders like gammarus in your system
3) you have no means of blasting the particles from the bottom of the tank up toward your plant roots.

Just FYI, if you use metal tanks for anything, they must not have zinc or copper in them due to being toxic to fish.

So much help!
Lots of my questions answered here!

Awesome videos! What type of greenhouse do you have?
What I was looking for. Thank you!
very educative
Are there any concerns of microplastics being present in the fish that we rear for consumption due to the use of K1 and other plastic filter media?
Maybe large scale but not here
@NewAgrarian Glad to hear that because I'm using K1 media in my small-scale systems. Cheers.
any particular advice if using a DWC to grow marijuana?
Great explanation 👍
can you put the plants with the fish
Not usually, many fish will eat plant roots
Great setup!
where do you get settling tanks from?
It's sounds so confusing
I wonder if K2/k3 would work like in fish aquariums sir
Great video! I love the diagram, so helpful!
What do you think abt ast bio filters
Don’t have experience with them. Looks like they could work though
Great video. Love it. Hope one day a bit the space for an aquaponic system
Perfect, the best explanation about Aquaponic Systems
🤘🏼🤘🏼👍🏼

They use the nutrients that are extracted from waste. Not the waste itself
so much stuff to learn!
Great Video
So, with grow media beds, are the steps all the same? I was thinking the media would act as a filter
Yes. I discussed this in another video

How many days/ weeks before you change water?
I don’t really… I just add water when it evaporates .. could be a month

hey, have you figured thus out. would really love to learn a few things from you, if you don't mind.

I have a question Why cant you just put mesh bag direct into the main fish tank? Why It has to be in the Filter?
You could, it would work that way. Just may get particles on it from food or fish waste, or clog outlet pipe
@@NewAgrarian thank you!
What is these white thing covering the tank called?
PVC sheet
Would you say DWC is the best method for ease of cleanup?
Yeah or NFT if you can get adequate filtration
@@NewAgrarian NFT Aquaponics would be awesome
What pump do you use??
Sweet water high efficiency pump, 1/2 horsepower.. it’s a few years old
@@NewAgrarian link for this sweet water pump
