Improving Water Quality - Liming
 Liming fisheries serves a number of purposes:
- Decreases organic and oxidisable matter;
- Increases oxygenation by stimulating of aerobic micro-organisms;
- Improves water clarity by settling suspended solids;
- Reduces methane production in silt bodies;
- Counteracts acidity in water and hydro-soil;
- Provides essential calcium, increases alkalinity and conductivity;
- Increases water transparency;
- Reduction of orthophosphates, and iron ammonia salts,
- Reduction of disease in aquatic organisms
Liming using calcium carbonate or calcium sulphate benefits sport fish populations in many ways, improving overall water quality and fish health in acidified lakes and ponds. Fish in acidic waters are stressed, have lower resistance to disease, and grow more slowly to a smaller maximum size than fish in alkaline lakes. High acidity and toxic metals kill fish eggs and larvae and reduce spawning success. Liming can neutralise acidic waters, minimise stress, and detoxify heavy metals.
Liming of lakes and ponds to treat the hydro-soil and neutralise pH has become commonplace and the A.G.A Group are at the fore-front of this technology using lime professionally to both sterilise and to treat acidified ponds and lakes.
It should be noted that liming can only work in certain areas and working, as we do here at A.G.A Group on the precautionary principle would only recommend it in certain cases.
