Advantages

1. Disinfecting Effects
2. Generate oxygen during degradation
3. Eco-friendly
Sodium percarbonate is non-toxic, environmentally safe, biodegradable, and leaves no harmful by-products or residues which can harm the environment. It is also non-toxic to animals, plants and humans.
4. Chlorine-Free
Sodium Percarbonate is not a chlorine bleach, instead, it is an environmentally friendly version, known as an oxygen bleach, that is safe on colours, whiten whites, and as an added bonus, does not weaken fabrics like traditional bleach.

Sodium Percarbonate(SPC) can be used to improve water quality by the indirect addition of oxygen and associated elimination of bacteria. As a side effect, it purifies the bottom in concrete raceways in hatcheries, and cleans up the sediment in earthen ponds when SPC reacts with the organic matter.
Water treatment options for organic aquaculture are restricted, compared to those available to conventional fish farming; only easily degradable disinfectants are allowed. One of the permissible water disinfectants that can be used in both conventional and organic aquaculture production systems is sodium percarbonate (SPC). SPC is a dry, granulated form of hydrogen peroxide (H202), being a crystalline adduct of H2O2 with sodium carbonate
The advantage of applying SPC over other H2O2 products is that it is safe and easy to handle. Being a granulated tablet, it can be evenly distributed in a pond.
