MasterLine Liquid

Masterline was founded in 2016, but the first tests for aquarium plant fertilisers began back in 2006. At the time, founder Marian Sterian fell in love with the sheer variety and beauty of gorgeous underwater plants. Since then, the company's effective aquarium plant fertilisers have become a firm favourite among aquarium enthusiasts around the world.
