....your right 'us guys' would do it...

Lets keep using my 'off the wall' visual in the above post...in which I used 1 million pounds of azomite. And add your statement to it...
(I'm really tired....hope this makes sense...and hope my math is correct.. )

You said soil has 'a few' ppm of uranium....let's say 2. In order to get my backyard system's water up to 2ppm, a natural level...I would need to add 'x' pds of azomite...?

A cubic foot of the stuff is 48 pounds...a million pounds would be aprox 20,833 cu ft.
A gallon of water is a cu foot.

My backyard system is (just over) 2,000 gals/ cu ft....so my system's water is aprox 10% of the volume of the 20,833 cu ft (1 million pds of azomite)

Adding 10 % of azomite would give me 4 ppm, so I need to reduce that to 5 %.

In order to get 2 ppm of uranium into my system, a natural occurring level in soil....I would need to add 1,042 cu ft... 'or' ...50,000 pds of azomite to my backyard system.... .....wow, is my math correct ?

So, I'm wasting my time adding banana peels to my media beds....oh well, the worms love them...

UF, What could we use, to add sodium to our systems (something 'cheap' and natural)....and how much per 100 gals to add 1 ppm ?
