PPM, I really need it..

Can anyone please give me a website or tell me what ppm is? Ive look at the FAQ and it just doesn't explain it good.

Listen my ass is old and i know what it means.

So how old are you?

lol, not old enough, please help or dont post.

parts per million. tells how concentrated a solution is bra.

Thz, i kinda see... can you back that up tho?

what do you mean back that up? it's parts per million, period!

LO fucking l I am old. I thought you were talking about personal message.
It is parts per million. I can back that up.

pretty puny matter

Ok so lets say you have 1 million CC of water. ok and you take out 500 cc of water and replace it with salt. now you have 500 cc out of 1,000,000 cc or in other terms 500PPM (Parts Per Million) the higher the PPM the more salt in the water.

Finally!!! NoDrama , thank you! that's what I mean.

you can also measure using ec which is electrical conductivity. Pure water should have no conductivity so as salts(nutrients) are added they are conductors and can be measured in the water using a meter. My meter measures the EC and PPM.
