Backyard Aquaponics
A place to discuss aquaponics

How are you going to keep the trout in the water.

They like water duff
There are net covers and waterfall mesh screens

C1, what an awesome system you got there. Sounds like it will work great too. You may find there is some solids buildup in the FT's maybe not. Purely from an aquaculture standpoint I wonder what provisions you have, if needed at all, to cleanout or repair certain segments of the system without shutting the whole system down. Bypass lines etc. You could always drop a submersible trash pump into the FT's to cleanout solids.

I have learned the hard way that on a large (Recirc. aquaculture) system its better to run two smaller pumps for redundancy. If you lose one main pump with no backup aeration and 1000 kg of trout you my have to rent a dump truck. Of course if you losepower without a backup generator all lost anyway. One way around backup power is compressed oxygen.

Keep up the great work.

Just a few of my fishy thoughts for what its worth. Trying to save some grief not cause it.

Each FT have a central drain if need be and conical bottom.
It work well thanks for your comments.
Also we can isolate banks of 4 GBs or totally isolate GBs from FTs.
Running independant FTs or isolate sump and second FT etc.
Lots of thought went into it

Good to hear, no question alot of thought went into it. Figured it had something I was overlooking.
Does it run on one pump and or have backup aeration? I probably missed that too.

There are 2 pumps, they run alternating duty cycles
maximum pump failure outage 1hr.
We don't believe we need extra airation as the waterfalls x 3 plus return drop x 2
I have thought about adding a venturi(s)... somewhere
Soon a genset will be added with auto start on power failure

Super. Although, the possible hour without aeration/pumping might be a concern. I really look forward to seeing pics of it in operation.

Nah, lots of ppl pump for 15 and drain for 45 and have nowhere near the airation capability
of 3 water falls etc.
Yes I would like to see the pics on here too

C1, Great job on the system. Has got a serene feeling to it.

I would love to have something like that in my backyard as well. Only problem is space.

Hehe, space is only an issue if you make it that way

Looking good...

So what size pumps did he end up going for Ivan.

8000ltrs/ph

I tested the water today.
ammo .5 ( I dumped a few 100ltrs of high Ammo from my system a week ago)
Nitrite has a trace, barely noticable.
Also seeded with some hydroton from my system

Ammo still at .5
...trace of nitrite (prolly from my water too)
pH7.4

same results today
Still no pic
