Toru-Active is the natural pH reducer of pond water, based on peat bogs. The peat is concentrated and pressed into \'pellets\'. It is 100% environmentally friendly and is biodegradable.The humic acids lower the pH value and the trace elements enrich the pond water. In addition, humic acids protect the living environment of the fish and plants and largely determine the biological balance. Toru-Active inactivates chlorine, which is still added to tap water in many countries. That is why it is particularly suitable for new ponds.Natural ph reduction for 5000 litres of water on the basis of peat.
