sera toxivec FreshwaterOptimize water parametersCare First aid in aquariums Immediately removes ichthyotoxic ammonia and nitrite Binds heavy metals such as lead and copper Removes chlorine and chloramines Lowers nitrate levels and, correspondingly, algae growth Due to destabilizing factors (including overfeeding, high fish density, new setups, larger maintenance efforts or using treatments) massive pollution peaks by ichthyotoxic pollutants such as ammonia and nitrite may suddenly occur in aquarium water. In such emergency situations, sera toxivec immediately removes these toxic substances as well as other dangerous substances such as chlorine and heavy metals. The natural equilibrium quickly reestablishes after having removed the pollutants without the necessity of repeated stress causing large water changes. Recommended dosage Add 5 ml sera toxivec for every 5.3 US gal. (20 l) of water in case of acute pollution with harmful substances. In case of higher pollution levels, up to five-fold dosage of the very well tolerated agent is possible, and can be repeated if necessary until the parameters have become normal again. Some soft leaved plants may react sensitively to the product.
