JBL DENITROL – Bacterial Starter with Enzymes for Freshwater and Marine Aquariums, Safe Start and Clear Water
Bring nature into your home – A habitat for fish and plants
JBL Denitrol is a powerful liquid bacterial starter enriched with natural enzymes, designed to create a biologically stable and safe aquatic environment from day one. Ideal for new tank setups, water changes, and post-medication recovery, Denitrol introduces eight live, highly active bacterial strains to rapidly kickstart the nitrogen cycle and eliminate harmful substances such as ammonium, ammonia, and nitrites.
The included heterotrophic bacteria efficiently break down fish waste, organic debris, and nitrogen compounds. Their combined action ensures fast biological stabilization, preventing toxic spikes that could harm aquatic life. For best results, use JBL Biotopol 15 minutes prior to Denitrol. Fish can be safely introduced the next day, as the bacteria quickly multiply in the presence of organic nutrients.
