3 pack of Biopronto FW - Rapid Cycling Culture for Freshwater Tanks (125 ml) - Two Little Fishies

Once upon a time the way to start a marine tank involved introducing a few hardy fishes and waiting until the tank “cycled.” The wait to establish an active biological filter often lasted one to two months, until now! The startup of a freshwater aquarium has never been quicker or easier! Two Little Fishies BioPronto Freshwater contains cultured naturally occurring microbes that rapidly start the biological filtration process. Use it to start the nitrification cycle in new aquariums or to enhance nitrification and denitrification in heavily stocked aquariums.

For Freshwater use only: 125 ml size.
