Les,
Last autumm I couldn't get
oak leaves but managed to get Beech leaves which I beleive serves the same
purpose. A few months ago I aquired a group of adult Taeniacara candidi
and wanted to lower my pH in their 36" tank. Using the leaves the pH
gradually lowered to the level I wanted pH4.8. The leaves make a very
pleasing sight as the adults and fry have plenty natural cover. I also
used the leaves in my Crenicichla regani (dwarf pikes) tank as they also require
a very low pH.
