Neutral 7 - Weakly acidic 6.5.
Ponds don't need to be strongly acidic because they will harm the animals living inside it.
keep the pond and the creatures in it safe and healthy.
A pH meter
A pH level between 6.5 and 8 is considered healthy for human body. In a pH balanced body, urine is slightly acid in the morning, (pH = 6.5 - 7.0) generally becoming more alkaline (pH = 7.5 - 8.0) by evening in healthy people primarily because no food or beverages are consumed while sleeping.
Nope. Blood ph is allways something like 7.35 on ketosis if you are a healthy person without diabetes
I'm almost certain there is a difference. If you want to find out the PH of each of them use universal indicator paper. then you will know whether each of them are an acid or a base.
The average value is a pH value of 7.0-8.5, depending on the location.
You can but with my experience it will lower your pH,my pH was at 7.8 then i add sand it drops to 7.
pH 9-10
The approximate pH of a healthy kiwi is about 7.4 No its not. Its 4.5
pH range for Koi is 6.5 - 8.5. Outside of this range they will endure stress.
If your pond pH is between 6 and 8 it will be OK. If it is below pH6 then you could add some Bicarbonate of Soda (Sodium Bicarb) but only a tiny bit at a time otherwise you could easilly kill the inhabitants of the pond with pH shock.
Stomach pH at digestion is 2.
This depends on the application.
keep the pond and the creatures in it safe and healthy.
There is no "body pH." Different fluids of the body have different pH.

well actually it does i am working on a science fair project and you can tell whether or not your pond is healthy is by their malformations.
