Big Aquaponic Greenhouse - Part 10 - Design Details! 

Also more even flow distribution to all the beds.

sounds great!

yes, there is space for that on each end.

I'd guess without the remineralisation tank the solids would build up in the media beds and clog the expanded shale, probably wouldn't be a big problem and would just require more regular cleaning of the shale/beds. The remineralisation tank would also lower the soluble organic content by having bacteria eat it which would then settle out and get wasted as sludge, I'd guess that if too much organic went into the media beds then more bacteria would grow there and similarly clog up the shale faster. There'd be some nitrification of ammonia to nitrates in the remin tank too, but I doubt Rob chose to include it for that as the media beds should do the nitrification

I agree. That's one of the reasons why I also have that emergency overflow pipe in each bed so that there is a vent next to each siphon

there will be a narrow plank along that area if I have to get to anything. Mainly it's designed to plant on one end and harvest on the other.

Bigelow Brook Farm (Web4Deb) I see. That makes sense to me now. Thanks!

Cavin u still here buddy???

@@ASTRO-ri6ex Yes.

@@GavinFish hey buddy hope ur doing good... I want some tips about aquaponics.. I know the basics and stuff but i would love to get some help cs im struggling all alone building my own system.. So i thought ud help me stand on my feet by getting on contact on social media or something 😊

Did u find the answer????

What I have done is add MMBR in the mineral tank, doesnt cost much and is one time investment.

The media beds act as the bioreactor. Plus is creates an environment for the red wiggers and my longer term plants. It will also work by gravity so I don't need the waste the power on an air pump

I kept all the piping between the beds and DWC above ground to prevent anything from settling in them.

That is exactly what I was going to ask. There is no direct access to one side of the 1.2m bed or both sides of the 2.4m bed. Initially it seemed like a design flaw but as a lot of thought has gone into the rest of the system, it's hard to think that he made such an error.

The overflow pipe next to the bell siphon acts as a vent.

@@Bigelowbrook That's fantastic! I assume you're also using your 3d-printed bell siphons so that the breather tube assists the break? Does the overflow have a one-way valve to prevent water from the vacuum coming back into the media bed? Or does the pressure from the outlet pipe keep it from coming up the overflow?

you want to suck the air out. If you have on blowing in, it can balloon the plastic

Bigelow Brook Farm (Web4Deb) I thought the idea was to circulate and remove the hot air by sucking in fresh air from outside. I’ll go with what you’re saying. Cheers 👍👍👍

there is no sump in this, just one pump

@@Bigelowbrook If you run a sump you can use the system as a hydroponic hybrid If you want to bypass the fish tanks for a while for any reason. Or bypass the beds for maintenance etc.

Blow them out with compressed air, just like a lawn sprinkler. I just keep the pump running all the time.

ram pumps are very inefficient. A settler is different than a swirl, you want to use a settler.

Bigelow Brook Farm (Web4Deb) that’s great. Thanks for getting back 👍👍👍

It depends on the plant, some plants need more space than others.

hi guys, the greatest success that i've ever had was with the Keiths Ponics Site (i found it on google) definately the best course that I've tried.

From poor memory, it has 200 gallon/hour going through it so that would then be around 1000 gal/hour go through the drain. I would have to measure it again to confirm.

@@Bigelowbrook my concern was the diameter of that SLO pipe to flow rate. You may get settling in the pipe. I know I got that now in my setup due to not enough head from fish tank to RFS.

@@mattolsson8816 yeah, I've been checking for that. I have the valve on that line mostly closed to keep the flow down but I can pop it open to flush the line. So far no big chucks have come through. We'll see what happens when I start loading it up with more fish this spring!

@@Bigelowbrook it took a while for bacteria to grow in the pipe. Heat will speed that up. Just beware. Lol. I just spilled fish poop all over the floor of my RAS shed when cleaning that pipe. 😁

@@mattolsson8816 I just ran into a clogging issue with my radial settlers as well. The outlet back to my sump was fully clogged, but it was easy to clean. Just one more thing to remember when I expand my system. Watching these videos is helping me plan my own system while seeing how he met some of the problems I have run into as well. 😁

in this case he will have to raise the ground around the fish tank . because half part of this system is like ''gravity feeded ''

That's a fallacy, temperature differentiation in the ground starts around four feet deep and it has to be enclosed with dirt. You place the tank in the ground to lower the surface level, not for temperature.

he said it like 20 times and it says so on top of the screen for literally the entire duration of the video
