Question about Buffering Capacity in pond!

OK, so I got a pond kit to test my bond.
I read it as the ph level was too high and the total buffering
capacity was too low. According to the instructions I have to add
Sodium Bicarbonate (baking soda) to bring it up.

My question is, is the standard baking soda in the grocery store ok to
use as long as I just get pure baking soda? If so how much should I
add?
My pond is about 2000 gallons.

Thanks for the info.

Add one or two of the smaller packages of supermarket baking soda and
re-check the pH. In a lab the pH would be above 7.5 for a solution of
baking soda. It is also usual to add some calcium carbonate for hardness
too. That also provides some buffering.

Grocery store baking soda is what we all use. Start with 2 cups worth and
recheck after 24. hours, depending on circulation YMMV. I'd liked to know
what your pH is? Baking soda has a set point of 8.4, some say it will bring
down a pH higher than this.

If anyone out there has experience with bringing down a pH with baking
soda, I'd like to know just how much does one needs to add? I've used up to
2 pounds in 1,000 gallons and didn't see the 9+ pH budge. Testor goes to
9.5 so I had the range to know just how high it was. ~ jan

Jan, register here (http://www.click2roark.com/ ) and check out the
carbonate calculator. It will calculate how much you need to add based on
current ph and pond size as well as the target ph...

you bring it down with HCl, not baking soda. Ingrid

That's what I've been doing. ) Many people claim that baking soda will
bring it down, and I was wondering if anyone here had experienced that
phenomenon. Perhaps it is another wishful thinking myth? ~ jan

Something I picked up he
- if KH is below 150 ppm or so, adding baking soda will raise KH and
shift pH down towards 8.4. Suggested dose 1/3 pound per 1000 gallons.
That will raise KH by 20 ppm. or about 1 degree. ½ pound per 1500
gallons.
- if KH is above 150 ppm or so, adding muriatic acid will lower KH and
shift pH down. Suggested dose 2 ounces per 1000 gallons.(per day)
Add acid to water, never water to acid!

So what is your KH?

Regards,

Hal

I added 1 lb of baking soda to 1,000 gallons giving me a KH of 179-200 ppm,
the pH, if anything, went higher into the 9s. Will check out the carbonate
cal. at Roark site. ~ jan

OK, your KH is above 150ppm so the stability of your pH readings is
assured. To bring down pH and KH, use Muriatic acid that you can buy
at building supply houses and some good hardware stores. It is used
to clean cement.

If the KH reading comes from baking soda (sodium bicarbonate) it will
max at 8.4. If the KH reading comes from other sources such as quick
lime, or the lime in cement, it can go much higher, but HCL or the
commercial grade muriatic acid will directly consume the KH. Add
daily doses and check the KH to make sure you don't go below KH 150
ppm.

Hal

Plain old grocery store baking soda is the stuff. You say your pH is too
high, and buffering (KH) is low. The baking soda will bring the pH toward
8.4 from higher or lower. If the pH is at or near 8.4 then you can add a
pound at a time and see when the KH gets to about 7 dgrees or 100 ppm, which
is a good level. Up to 300 ppm is acceptable. If the pH is drastically
different than the 8.4, add just a small amount per day, raising or lowering
the pH no more than 0.2 per day.
