Dear Paul Wheaton, Saint of Self Made Men and Greetings Permies! I have something here that is very old and yet not utilized at all.
http://www.rose-hulman.edu/~moloney/AppComp/2001Entries/e09k/fountain.htm ***1

It is Herons fountain and in it we perpetually utilize Bernoulli and pascal theory's on liquids. the link above is not quite perpetual but has the equation (which im not quite sure about)
(***2) this is the improvement and perpetual fountain

Okay.. So I think that this could be very very useful in aquaponics, for obvious reasons. Is there anyone out there that is goo with the algebra? I know rho is density of water. im assuming 'g' is gravity. is that force exerted? ft.lbs? how is'g' quantified?

H1/H2 would be nill and void in the adaptation where vessels b and c are equally pressurized?? how does that change the equation?

I also want to adapt a bell siphon inlet to first vessel c from the main fish resevoir. im assumin a check valve would be needed here. Im going to caveman engineer a working version with five gallon buckets giving what i assume would be a volume of 2.5 gallons at (v). who can solve for V??? ***1. given two five gallon buckets on equal height as in ***2 winner gets a free peach tree(?) or transplant of equal value (subject to availability) )))

Makes perfect sense, thank you. Less variation than apples and some have been stabilized. What about the grafting though? the root stock shares expression or just feeds the graft?

Curious if anyone knows if peaches breed-true or if there is a genetic variation between parent and offspring like in apples, requiring a graft. do you have to maintain a mother the graft her to the rootstock to maintain her expressions?

Update: I found that the limestone apparently helps to even the waters pH to a neutral 7 due to its containing some calcium bicarbonate as buffer (http://www.water-research.net/Watershed/alkalinity.htm). thought this action may be for a limited time... as for the extreme flooding i made a
40\10\50 mix of limestone-gravel\verm.\"ky brown" gravel and lowered my standpipe a bit. I put it 2.5 inches below media level and everything is grreat. this system is really cool. completely sustainable as long as the pumps are solar/other renewable.

Greetings all. Im setting up a new aquaponics set up. I chose the side-by-side half barrel type. For media I used what also I had Lying around.... some white limestone gravel from a walkway. this was running short so in a pinch I grabbed some vermiculite. I added about two or three inches to the gravel and mixed in a little. I suppose I underestimated the water retaining power of the little gold devils because now my bed is waaaay flooding.... i suppose this will be good if i can add a timer to my pump and maybe flood once a day or so... ANY thought on THIS? Also, and the reason Im writing... any experience or thoughts on the pH of limestone treated water or root contact? am I risking a lockout by using this gravel? also what about the muddy intial state of my flood? it clears up pretty good after the bell starts flowing but man its soupy at first.... maybe I could mix in say half another gravel? we have some brown solidified clay type stuff here in KY that's readily available and probably more 'inert' than the limestone... thoughts any one?
Thanks

Im not to sure about the benefits it brings soil, myself , but logic would point to action like the dandelion. I say grab a couple seed and see how big you can get the thing! Mullein has lots of uses in medicine. the leaves make a good cough tea, the roots good for bones and arthritis, the the seed contains a natural pesticide called Rotenone, so dont eat them.

Definitely. We're doing yukon gold and red pontiac in straw layers on top of compost. they seem to be doing great!~

Charcoal seems like it would be a great medium, never thought of it! it holds lots of water and filter all sorts of stuff out of water. does it release its nutrients or are they locked inside the carbon? i guess it depends on ionization?
