01 — Benefits
4 main benefits
- 01
Removes alum and neutralises heavy-metal ions that pollute the water and pond bottom soil.
- 02
Cleans gills when shrimp show yellow gills or legs after alum leaches from banks in heavy rain.
- 03
Helps with environment-related black gills and yellow gills when NO2 is high.
- 04
Reduces water hardness (Mg, Ca) and balances ions and osmotic pressure when hardness or salinity is too high.
