KH, GH, pH ... oh, my
Okay, so I didn't listening to JMK and I messed with my pond water
today. Sorry, ;-) Reminder -- I have green algae water and test results yesterday we pH: 9.5 NO2: less than 0.3 ammonia: 0 GH: 1.5 dH or 19 ppm KH: 2 dH or 36 ppm CO2: 0,1 (based on a chart analyzing pH and KH) I added one cup of baking soda, then realized that if I did nothing to bring the pH down that the baking soda would increase the pH. I have muriatic acid on hand (for pool and cleaning aquariums) so added ~6 ounces. After two hours did the following tests: pH: 8.5 GH: 3 dH or 54 ppm KH: 5 dH or 90 ppm So if I add another cup of baking soda tomorrow, the GH and KH will / should increase again, but because I'm stabilizing the pH with the baking soda it shouldn't increase and might even decrease? [Before I add anything, I'll retest pH, GH, KH and ammonia in the morning.] As I lowered the pH today (and the GH and KH increased), the water seemed clearer. Does high pH water hold algae or other fine particles better than lower pH water? If GH is a measure of calcium and magnesium, why does it increase by using baking soda?

zookeeper,
Just get the KH up into the 100's. The pH will go to 8.4 and No Higher or Lower. Don't fool around with the pH!! You can fool around with the GH later... not important now.

If GH is a measure of calcium and magnesium, why does it increase by
using baking soda? [Little rusty on chemistry, especially at 12:02 am.] It shouldn't. Never has noticeably for me. I went from 2 KH to 9 KH with Baking Soda and little/no move in GH. |

Why is your PH 9.5? Is this a concrete pond or are there concrete blocks in
it? If you are trying to combat high PH you dont want to add a acid buffer like baking soda because you want the acid to drop your PH. Sam "zookeeper" wrote in message ...

Baking soda is the great neutralizer, no pun intended. It will take high pH
and drop it, and it will take low pH and raise it. Baking soda wants to be at 8.4, and if you get enough of it in the water, that's where your pH will be - whether it wants to or not.

Kathy,
Nothing that you added should have affected the GH. The GH test kit that I have is almost impossible for me to run, due to the colors green to yellow, or vice versa. There just isn't much definition, like there is with KH. Don't worry about the small difference in the test results. Don't add muratic acid, it just eats the KH. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "zookeeper" wrote in message ...

My GH test first colors the water red, then changes to green with one drop. Since I posted last night, I've googled rec.ponds on GH and KH, and read up on making the changes. Seems that if I keep adding baking soda my pH may go up or down to 8.4 and hold there when the KH reaches a level of 110 ppm or so. Will keep y'all posted. -- zookeeper |
