pH help needed
Greetings all,
I have a 2200 gal backyard pond with about 20 2-3 inch comets and koi and about 1/5 plant cover. This week my pH is at 6.5 How can i get it up to a good range. Can anyone recommend a good amount of baking soda or lawn lime dust to put in the pond to fix it. Could the pH have gone down due to a berry tree dropping berries in it all month? Thanks to all, joe |

pH help needed
If your pH normally runs higher, then you have run out of buffering and are
on the verge of a pH crash. You need to add some baking soda to bring the pH up, but do it slowly. Add a half a cup, wait about an hour and check the pH. If it has not gone up to above 7, then add another half cup and check again. Get a KH test kit and stop adding baking soda when the KH gets to be about 100 ppm or about 6 or 7 drops. At KH of 100 the pH should be about 8.2 to 8.4. It will be about the same pH at KH of 40. So once you have gotten the pH up above 8, then you can start adding larger quantities. There is a calculator at http://www.click2roark.com/. The site does require you to be a registered user, no cost though. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Tony Rivas" wrote in message . net...

Baking soda is your answer. It is a buffer which would result in a pH of about 8 when added in sufficient amount to overcome the acid. And, it's cheap. I have a 2000 gallon pond to which I add a pound of baking soda from time to time as needed. Calcium carbonate can be kept in a mesh bag to slowly dissolve and add hardness and some buffer capacity too but not as a remedy fix it. -- Jim and Sara Humphries, Victoria, BC "Tony Rivas" wrote in message . net...
