AQUA-Cal+ works as a water and pond bottom conditioner.
It aids in clarifying the water, controlling pH and releasing alkalinity as required, to aid in the digestion of organic matter.
Pond bottom condition improved
Iron problem reduced significantly
Reduction of ammonia, nitrite, and phosphate
Survival rate of shrimp increased
Shell of the shrimp hardened, and weight increased
A small shrimp farm in Parak Malaysia was struggling with decreased harvest weights, frequent sludge drainage and high iron levels.
The shrimp farm has 20 active ponds of earthen construction. The ponds are, on average, half a hectare in size and one meter deep, and are typically stocked with 100 to 120 shrimp every one square meter.
They typically take around 12 weeks to grow to a size ready for harvest.
A special formulation of AQUA-Cal+ was applied in this pond.
AQUA-Cal+ works as a water and pond bottom conditioner. It aids in clarifying the water, controlling pH and releasing alkalinity as required, to aid in the digestion of organic matter.
An initial AQUA-Cal+ dosage of 20 ppm successfully dropped the soluble iron in the pond and prepared the pond for baby shrimp, also known as “post larvae” (PL), introduction.
No probiotics or algaecides were used.
After one week, PL was introduced and after two weeks, the
weekly dosage of AQUA-Cal+ was adjusted to 4ppm.
The addition of AQUA-Cal+ at 20 ppm pre-treatment and 4ppm thereafter significantly increased water and pond bottom quality, controlling ammonia and nitrite as well as bottom sludge volume.
The improvement in the pond environment contributed to its health and subsequently to the shrimp size and harvest quantity.
AQUA-Cal+ is made by ﬂash calcining a mixture of magnesite and dolomite to produce a unique, very high surface area powder, and then hydrating the powder to produce a slurry for ease of application to ponds. It has been specially formulated to impact on both the aqueous and benthic ecosystems in the pond.Download the Solution Spec Sheet
