sera guide - Shrimps and crayfish

1919 For example, Red Cherry and Amano shrimps require a carbonate hardness of 4 – 16°dKH, Bee and Tiger shrimps an even lower range of 2 – 10°dKH. A carbonate hardness of 5 – 10°dKH is therefore in any case correct. Crayfish are usually adapted to environments with slightly harder water. If you need to lower the carbonate hardness due to hard tap water, you can do so by placing sera super peat (peat granulate) in the filter. This will also inhibit the growth of harmful fungi and bacteria. You can check the carbonate hardness with the sera kH-Test kit and increase carbonate hardness with sera KH/pH-plus if neces- sary. Amano shrimp (Caridina multidentata) Red Cherry shrimp (Neocaridina heteropoda var. “Red”) If in spite of all diligence the concentration of pollutants should quickly rise strongly, sera toxivec will immediately prevent acute intoxication of the animals in the aquarium.
