How to lower ph
I just checked the pond chem stats.
GH 75 KH 300 ph 9 Nitrates 0 Looks to me that the ph needs to come down and that that may be contributing to the problems of the WH. How do we lower the ph effectively in a cement pond? It is in fact higher than usual, generally, we have been in the 8 range. Speak, O pond muses. -- ____________________________________________ See our pond at: home.bellsouth.net\p\pwp-jameshurley Ask me about Jog-A-Thon fundraiser (clears $120+ per child) at: jogathon.net |

It is in fact higher than usual, generally, we have been in the 8 range. pH Down - - Muriatic acid (31% HCl) a doses of approximately 2 fluid ounces per 1000 gallons per day until the pH is about 8.5. I would not lower the pH below 8.5 without also testing KH (alkalinity). Acid directly consumes KH. If KH is lowered below ~100 mg/l, pH will become unstable, and the pH measurements become meaningless. Regards, Hal http://members.cox.net/hrclark1/Index.html |

I would not lower the pH below 8.5 without also testing KH (alkalinity). It will come down, but go right back up w/out acid. At KH of 300 and knowing its a cement pond... this pH ain't going anywhere unless its set up to a controller and a dosing pump. You could also paint it with a 2 part epoxy paint. Withstanding that, I leave it alone. jay Mon Jul 26, 2004 Acid directly consumes KH. If KH is lowered below ~100 mg/l, pH will become unstable, and the pH measurements become meaningless.

How to lower ph
I am stepping outside of my area of expertise, but the manufacture of sodium
bicarb is by taking sodium hydroxide, (soda ash) and bubbling CO2 through it so that the sodium + OH + CO2 yields NaHCO3. The concrete gives off calcium hydroxide and the hydroxide, if pure has a pH of 14, though as calcium hydroxide saturated it has a pH of around 12. I am guessing an excess of hydroxide is causing the pH to be high, and by bubbling CO2 through the pond the hydroxide would be changed to bicarbonates. Of course air stones would bubble CO2 along with the other components of air. Underwater plants produce CO2 at night, and in combination with air stones may help to lower the pH. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Jim and Phyllis Hurley" wrote in message ...

How to lower ph
Hmmmmm......
If the cement buffers it at its present level....and has been doing that for several years (since it was made)....then the ph will not be why the plants are yellowing this year! Less pressure on forcing the change. I will add some tomato fertilizer and see what that does.

This isn't a new pond, but an established one, with critters, is that
correct? If so, imo, how old is your test kit? Do you do regular water changes? What's the pH of the water you're adding? My lily pond went up way high, I tried acid, over & over, kept going back up. Tried 4 lbs of baking soda, nothing, still 9.2. Was told to do water changes more often since the pH of my tap water is only 7.8. Four water changes over about 8 days and the pH was back to 8.0. The most amazing thing? It's held ever since, I'm clueless as to why, but all the plants are doing great now. ~ jan On Mon, 26 Jul 2004 06:27:45 -0500, "Jim and Phyllis Hurley" wrote: I just checked the pond chem stats.
