I use 16 oz Baking Soda for every 1,000 gallons of pond water. I have a
pressurized filter
and I'm told this is what keeps the KH on the low side. (KH kit is very
cheap
($7 or 8 dollars)). Once you get the KH stabilized around 120 on up to 200
- your pH will even out at 8.4. I'd much rather use the baking soda than a
chemical.

if your pH is greater than 8.6, use muriatic acid, dilute it (acid into
water, never
the other way around). vinegar is useless, it is organic and broken down
too fast.
if the water out of your tap is not that alkaline, try to find what is
leaching into
the pond. Ingrid

Hi all,
Nubile is looking for an advice
What kind of chemicals do you use to lower pH in your ponds?
Yes, yes, I know, you buy stuff in local pond store.
Unfortunately, I do not have that kind of shop close enough.
However, I do have chemical store in my neighbourhood which provides
chemically clean acids.
Which of them is suitable for my pond?
I just do not want to harm fish and plants.
Thanx,
Tom
