Benefits of AQUA-Cal

Increased yield

Improved water quality

Reduction in other water treatment chemicals

Introduction

Calix’s Aqua-Cal+ is a special formulation of Magnesium Hydroxide enhanced with Calcium. It improves the quality of water and thereby promoting better and healthy aquatic life. Aqua-Cal+ is non-toxic, non-corrosive, safe to handle and environment-friendly.

BACKGROUND

Huang Xiaohua Farm is a large-scale farm with 1000 x 200m3 ponds all under cover.
They grow White Shrimp with 2 crops per year.
Stock Density is 120 pcs/m3 with 90 day grow out.
Harvest size is 20 pcs/kg

WHAT AQUA-Cal+ ACHIEVED

1. Increase survival rate to 95%
2. White Head disease was eliminated by improving water quality.
3. Harvest weight was increased by more than 20%
4. Other chemical inputs were reduced

Solution

Using AQUA-Cal+ at 20 ppm for tank preparation we enabled the increase survival rate from 85% to 95%.

Weekly dosage of AQUA-Cal+ at 4 ppm was able to increase yield by more than 20%.

AQUA-Cal+ also produced healthier shrimp and solved the problem of dark brown water with a significant pungent odour.

Conclusion

Rudong Huang Xiaohua where impressed with AQUA-Cal+ and have now become a sub distributor in the Rudong area.

There are 30,000 ponds using the same culture method in Rudong district potential for AQUA-Cal+ is 600 m/t p.a.

Farmers comment. “My shrimp are more healthy, water is now a nice brown green with no bad smell. I reduced my input cost and increased yield”

The application

AQUA-Cal+ is a special formulated high surface area Magnesium Hydroxide enhanced with Calcium designed for use in aquaculture ponds.
AQUA-Cal+ is a water conditioner and acts to improve the overall water quality while delivering a number of unique properties to protect and enhance shrimp culturing:
  • Reduces the water turbidity
  • Effectively binds the iron and other heavy metals to prevent metal toxic
  • Stabilizes water alkalinity
  • Recondition and stabilize the bottom pH
  • Reduces the hydrogen sulphide (H2S)
  • Neutralize the nitrites, phosphate and ammonia
  • Flocking and break down of organic matter in the system
  • Digests the sludge and create a clean pond bottom
AQUA-Cal+ is non-toxic, non-corrosive, safe, environmentally friendly and meets many core needs in aquaculture.

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.
