Other acids and CO2-pH-KH table
Adrian Banica recently asked what affect the tunnic and humic acids from
woods and peats have on the pH/KH relationship that allows extrapoloation
of the CO2 content. I believe George Booth replied that the impact of
these organic acids was probably negligible.
I only know that Ines Scheurmann stated that the presence of peat in a
substrate invalidates the pH/KH extrapololation. (Stated in her Auatic
Plants Manual.) But she did not explain the problbem. Can anyone else
comment?
And by the way, someone referred to Ines Scheurmann as a male person
recently--she's a female person! ( Estrogen also plays a role in aquatic
plant horticulture...)
