alanmin4304 Posted August 10, 2011 Report Share Posted August 10, 2011 Sorry, baking soda is sodium bicarbonate. You need to add calcium or magnesium ions to increase the hardness. Calcium carbonate (only realy soluble in acid water), Calcium chloride, or magnesiun sulphate (epsom salts) will do it but make sure you do it slowly or you will shock your fish.

ryanjury Posted August 10, 2011 Report Share Posted August 10, 2011 Yeah baking soda is for the PH, you need to add epsoms salts.. I add 1TBS of epsoms and 1 tsp of baking soda per 20L for my tangs.. Quote Link to comment Share on other sites More sharing options...
