Bacta-PurŽ XLG & Bacta-PurŽ XLG(A) for fresh water

(water salinity less than 5 parts per thousand)



  • Digest sludge and reduce toxic ammonia and hydrogen sulfide
  • Facilitate oxygenation
  • Reduce excess nutrients (nitrogen and soluble phosphorous)
  • Transform wastes into natural and beneficial food

Bacta-PurŽ XLG is a liquid suspension of balanced community of natural beneficial microorganisms, which have been selected for their capacity to biodegrade organic waste. It converts pollution into bacterial biomass, which becomes natural healthful food for fishes and invertebrates.

Bacta-PurŽ XLG(A) includes Bacta-PurŽ XLG together with Bacta-PurŽ ACTIVATOR 1 & 2. This product  allows a manual pre activation of bacteria before its addition.

The Bacta-PurŽ ACTIVATOR 1 & 2 are ECOPREBIOTICS™, essential nutrients for manual pre activation of Bacta-PurŽ XLG to maximize bacterial numbers and production of enzymes for digestion of organic solids. They do not contain the animal products. They are provided in small bags.
Treatment with Bacta-PurŽ XLG(A)
Ponds are treated with a combination of two products, Bacta-PurŽ XLG and Bacta-PurŽ N3000. One liter of Bacta-PurŽ XLG has to be applied weekly per 1,000,000 liters pond water. 

The application technique consists of preactivating Bacta-PurŽ XLG for 24 hours; Bacta‑PurŽ ACTIVATOR 1 & 2 with precise instructions are attached to each bottle. An equal amount of Bacta-PurŽ N3000 can then be added to the mixture. The mixture is then stirred for 30 minutes. It is important to diluate the mixture, 10-100 times, with pond water, before spraying or splashing over the surface of the pond, to assure an even distribution.

Recirculation systems
are treated with a Bacta-PurŽ XLG to reduce soluble organic materials and to help keep the biofilters clear of organic solids. The product is applied weekly at dose rate of one liter of Bacta-PurŽ XLG or Bacta-PurŽ XLG(A) per 1,000,000 liters of pond water .

Settling ponds are treated with Bacta-PurŽ XLG to solubilize the sludge and remove soluble pollutants. Four liters of Bacta-PurŽ XLG has to be applied per 1,000,000 liters of pond water. The weekly dose rate of Bacta-PurŽ XLG  is preactivated for 24 hours. The mixture is then diluted 10 to 100 times with pond water and is sprayed over the surface of the pond.
