This is a good, although scary reading on the use of sodium bicarbonate and PH crashes: http://www.koivet.com/html/articles/articles_results.php?article_id=206&category=12&search_term=bicarbonate\ I personally find that using 1 tablespoon per 500 litres of pond water will raise PH by 0.5 points on the PH scale.
