Maha Chemicals Asia had previously introduced a sustainable mineral technology, AQUA-Cal+, to alleviate the problems faced by shrimp farmers in Malaysia and Vietnam. AQUA-Cal+ is a stabilised suspension of approximately 60% by weight Magnesium Hydroxide with some Calcium Carbonate. AQUA-Cal+ utilisation in culture ponds minimises pollution to the environment and reduces stress factors in the ponds. AQUA-Cal+ enables farmers to adopt a green culture technique and increase yield and revenue for the farmers.

Here is the trial result from shrimp farmer in Malaysia. After adding AQUA-Cal+ into the shrimp ponds, the pH and alkalinity stabilized. Sludge digestion, water quality and pond bottom condition also improved.
