Holtfreter's solution
{{Short description|Salt solution used in biology}}
Holtfreter's solution (Holtfreter's medium) is a balanced salt solution that was developed by the developmental biologist Johannes Holtfreter for studying amphibian embryos and to reduce bacterial infections.{{Cite web|url=http://www.nasonline.org/publications/biographical-memoirs/memoir-pdfs/holtfreter-johannes.pdf|title=Johannes Holtfreter, 1901—1992. A Biographical Memoir by John Gerhart|website=National Academy of Sciences (USA)}} As a specialised aqueous solution, it finds use in aquaria to prevent infections for early stage amphibians, where it is typically mixed with soft tap water.{{cite web|url=http://www.axolotl.org/requirements.htm#hardness |title=Axolotls - Requirements & Water Conditions in Captivity |publisher=Axolotl.org |date= |accessdate=2011-03-29}}{{cite web|url=http://www.ambystoma.org/AGSC/axolotls/shortguide/solutions.html |title=Indiana University Axolotl Colony |publisher=Ambystoma.org |date= |accessdate=2011-03-29}} Amphibians such as axolotls prefer a hard water solution.{{citation needed|date=March 2013}}
