WATER SUPPLIES WITH HIGH PH,IN SOME AREAS CURRENTLY THE WATER SUPPLY HAS A VERY HIGH PH WHEN WORK IS BEING DONE.

CHECKED THIS FOR A FRIEND BUT MAYBE USEFUL FOR MEMBERS. How to Use Vinegar to Lower pH in Koi Pond
If your Koi pond pH is high, you can easily use vinegar to lower it. Vinegar is acetic acid which gives hydrogen ion (H+) when mixed with water. More hydrogen ion means lower ph. Therefore, when you use it in your pond, it will lower the pH by adding more hydrogen ion. In this article, you will learn how to use vinegar to lower pH in Koi pond in the right way.

What is the Ideal Koi Pond pH Level
Koi fish love slightly alkaline (basic) water. The ideal pH level for a koi pond is 7.5. However, koi can thrive at a pH ranging from 7.0 to 8.6. As you know, pH 7 is neutral and brings no harm to koi fish. But if the pH level is lower than 6, then there are great chances that your koi will die soon. The same goes for the pH level above 8.6.

You can’t strictly maintain a 7.5 pH level in your pond. Therefore, to keep your fish alive you should keep the pH level between 7.0 and 8.6.

You can use vinegar to lower pH? – How Vinegar Lowers pH

Vinegar is actually acetic acid. The acetic acid concentration in vinegar is in between 4 and 5 percent by weight. The molarity is 0.833.
Normally the pH level of vinegar ranges from 2 to 3. When added to water, this gives two ions – the acetate ion (CH3COO-) which is negative and positive hydrogen (H+) ion.

The higher the concentration of hydrogen ion, the lower the pH. Therefore, adding vinegar to your koi pond water will increase the concentration of Hydrogen ion (H+) in it. A higher concentration of it will lower the pH.

How much vinegar is needed to lower pH in a Koi pond?
The total amount of vinegar you will need to lower pH in your koi pond depends on two factors.

Size of your pond: This is obvious that for lowering pH in a large volume of water, you will need more vinegar.
Level of pH: Lowering pH means adding more hydrogen ions. Therefore, the amount of vinegar will also depend on the pH level of your pond. If you want to lower a high pH, say, from 8.7 to 7.5, you will need more vinegar. Again, if you want to lower a small amount of pH, say, from 7.8 to7.5, you will need a small amount of vinegar.
In general, it requires a ¼ cup of vinegar for every 500 gallons of pond water. But if you find the requirement is high, you should not apply more than this at once for the safety of your fish.

WARNING ,REMEMBER FAST SWINGS IN PH ARE HARMFUL TO KOI IF YOU HAVE TO MOVE PH DO IT GRADUALLY.

That's right Chris, yesterday some areas had something in the water that raised the tap water ph to 10.

At ph over 9 and below 6 koi can soon expire, pays to check the tap water ph before topping up especially if work is being done on water mains. Doesn't sound much different but a ph 9 is a hundred times more alkaline than a ph 7.

I personally have had incoming water with a low ph several times this year.

Think there is an old saying 'there is something in the water'.
