ncsponger said:Does anyone know if the aquarium product "Kalkwasser" is pure calcium hydroxide? SWIM can't find a definitive answer. It seems that calcium hydroxide is the primary component of kalkwasser(90%?) but SWIM is wondering if it might contain other undesirable materials. Thanks for any help.
"Seachem" brand kalkwasser is very pure Calcium hydroxide. Kent Marine brand is also supposed to be very good. In general, quality reef aquarium products are more pure than food products. Some reef aquarists will not use edible lime in their tanks. Any impurities present in a regular supplement will accumulate over time.
