Backyard Aquaponics
A place to discuss aquaponics

I am glad we got the clarification on the split flow system.
Like cookie it is my intention to have a split flow system with the appropriate mechanical and biological filtration.
There are a number of advantages to it in larger systems.
Its not CHOP anything (bloody stupid acronym).

Aahaahaa lol.

True but he didn't talk about any components to filter water either and you don't see many original CHOP 2 systems with these components. Of course then they had problems with fish health and solids which is another reason why we have seen such a proliferation of RFFs and dedicated biofilters. Not that there is anything inherently wrong with using these components but so often they are added without any real understanding of their purpose, use or design.



First of all CHOP 1 === CHIFT PIST. Someone on here came up with the ridiculously awful acronym CHIFT PIST and then later the design was relabeled to CHOP by an ex forum member when he started to sell CHIFT PIST kits.

It may be possible to make such a design reasonably efficient but to my knowledge no one has. Essentially you create two different duties that you try and get one pump to fulfill simultaneously. If you could make the two duties of equal dynamic head without creating an unnecessary restriction then it could be just as efficient as a CHIFT PIST but that is one huge if.

A way to do this may be to use above FT water jets where a restriction (Jet) increase the velocity at which the water enters the FT. IF the outlet is above the water then the aeration from the entrained air may increase the efficiency of the system compensating for the increased total dynamic head. The thing is though that getting the balance roughly even would be a massive challenge in the first place but any changes in anything would stuff that balance. This means that the whole idea of being able to expand willy nilly is out the window. As is any ability to vary flow which you would need to do as stocking density or feeding rate increased plus you wouldn't be able to reduce your aeration energy spend during cool weather.

Well you could but the level of control that you would need to add would make the system much more complicated. Plus you still can't get away from the the mixing of the water. If water from the FT even if it is filtered is going to the sump and water from the plant production components is going to the sump then the water will mix. This means that water will go back to the plants only partially recharged with nutrients. This may not be a problem for certain crops but for heavy feeders you would have to run the water in the FT at a higher nutrient concentration to get the same equivalent nutrient concentration that you would in a CHIFT PIST system.

Quite frankly if you are going to make a split loop system why join the systems at the hip, so to speak. We don't know much about Ryan's commercial system or the UES system but their advantage is increased control of nutrient solutions because of the division between the two forms of production.

In a BY setting it probably doesn't matter too much but why add so much complexity. If you want to do it just for fun then OK its a hobby so what ever you enjoy. I've got a friend who goes out and gets his 4WD bogged to the axles on purpose It doesn't make any sense to me and he has fun, each to their own as long as he doesn't try and make a case that its the most efficient, best or even good way to get from point A to B I can feel comfortable looking on in bemusement.

Well we all have our own opinions.

Yep.

True.

LOL

Which bit?

My statements or Sleepe's?

lol both.. im a passives most of the time

I cannot agree too nor deny with the previous views.. I love politics

And Blizzard what Charlie says is correct. we are here to discuss and debate all that is aquaponics and that alone. leave it to Jerry Springger and MTv to discuss personal feelings.
Jerry! Jerry! Jerry!

Thanks cookie I get the drift!
My system is Orr some to me, I put a new vid up on here,
Really I just wanted to help the new people on here, I am new too but the info I was looking for was not on here? I watched hundreds off clips to get the idea off the system I built for myself, I even worked out a filter that will be needed in the future, I just want to make sure it works now before I start a DWC system addition, for seed propagation, I am thinking years ahead here! But at least I am thinking?

Thanks again cookie!

np but exactly what are your concerns..? I may be able to assist you a bit. I may not have all the answers but I'll approach it logical and factual.

There should be a TV show for AP build-offs. It'll be educational, confrontational and competitive all at the same time.

We need a title.

I have just reread Stuarts last long post so I vote for AP (Assumptions and Presumptions).
