Fast delivery of Ensan Blue 5 liters of waste water addition and a neat package. After using the product I'm thrilled. The scent is pleasant and the liquid takes place the decomposition of feces thoroughly. For years I have the liquid Aqua Kem Blue benutzt.Dieses product is much more expensive than Ensan Blue, but not effective in the decomposition of Fäkalien.Ich remain available for the product Ensan Blue.
