pH value of Rio Nanay.

[noram]

I recently got a Ap. Bitaeniata male of Rio Nanay.

I may have wondered.

It is a question about the pH value of the Rio Nanay of Peru.

On 37 page of tetra book, It have been written that pH value of Rio Nanay is pH3.9, Is this correct?

I know that pH value of rivers are changing, so It might was pH3.9 when it is measured.

But I think that value is too acidic.

Does anyone know about the pH value of the Rio Nanay ?

Hi all,

You are right pH3.9 is just a number, and it is "too acid", but the Rio Nanay doesn't really have a pH value, it is a "black-water" river, so it will always be acidic due to the humic acids and lack of any carbonate inputs, but that is about all you can say.

Member TomC visited the Loreto region in 2007: <http://apisto.sites.no/page.aspx?PageId=60> and has made a number of visits to the area around Iquitos, there will be water values in his travelogues.
The problem is really with using pH to measure the acidity/alkalinity of water with little or no carbonate buffering (dKH) and very low amounts of dissolved salts (conductivity in microS or ppm TDS). The pH value will fluctuate wildly, although the actual change in the balance between proton (H+) donors ("acids") and H+ ion acceptors (alkaline or bases) will be very small.

Have a look at these threads: <http://www.apistogramma.com/forum/index.php?threads/700-liter-amazone.13197/#post-71460>, <http://www.apistogramma.com/forum/index.php?threads/ok.12048/> & <http://www.apistogramma.com/forum/index.php?threads/keeping-low-ph.12720/#post-69837>

pH measurements in Peru vary greatly. When I have visited at the end of the dry season (October) pH measurements within the river drainages can be as low as 3.5pH but never more than approximately 6.0pH. They are generally highly acidic waters. ...
The Rio Nanay drainage, where your A.bitaeniata are found, is the same. I would try to maintain a pH of approx 5.0-5.5pH for these fish.

Hi, dw1305

Thank you for your answer.

You taught me a great website, thank you.
It's very fun!


I've read your commentary.
You gave me a very easy-to-understand explanation for me, thank you.


Those threads that you taught me, for me it was difficult to understand.
But it was very interesting.

Thank you very much!

Hi, Microman

Thank you for the explanation.

Oh! you have been to the river of Peru!
I envy you very much.
Someday, I want to go to the site, too.

Indeed, the pH value of the Rio Nanay It seems lower than I was thinking.
Thank you for writing valuable experiences.

Thank you very much.

Same here, I should have said that both Mike Wise and Microman have both been to Peru with TomC.

Hi dw1305,

I didn't know that Microman have been to Peru with TomC!

I think that travel was really nice!

Thanks for your information.

good night!
