BioPronto Marine is a new product you should reach for when you need to kickstart a new marine aquarium or system. Two Little Fishes has been on a roll releasing new aquarium management products lately, like Bactiv8 NPX and now BioPronto Marine. Whereas Bactiv8 NPX is a food source for heterotrophic bacteria and the removal/export of nutrient like phosphate and nitrate, BioPronto Marine is a classic starter culture of beneficial aquarium microbes to rapidly start the biological cycle. BioPronto Marine can get your aquarium up and cycled in a hurry or it can also be used to enhance nitrification and denitrification in aquariums with a few extra fishes, and it can also dissimilate toxic ammonia in a pinch.
