Rapid Cycle Specialist
Your pond’s biological filter is its most important line of defense against toxic fish waste. Colony® Freshwater contains live, commercial-grade nitrifying bacteria that help establish biological filtration in days instead of weeks.
Formulated with freshwater Nitrosomonas and Nitrobacter, Colony supports the natural nitrogen cycle by helping convert ammonia into nitrite, then nitrite into less-harmful nitrate. This makes it an excellent choice for koi ponds, goldfish ponds, ornamental ponds, water gardens, and quarantine systems.finestaquatics.co+1
Use Colony when starting a new pond, adding fish, replacing filter media, restarting a filter, or following medication—any time your pond’s beneficial-bacteria population needs support.
