2Hr Aquarist

The story of The 2Hr Aquarist begins on the sunny island of Singapore, at the crossroads of East and West and one the world’s largest trading hubs of aquarium fish and plants. In 2015, well-known aquarist and aquascaper Dennis Wong started a youtube channel to share his techniques in growing aquatic plants and long-term maintenance of freshwater aquariums. Followers started experiencing the results that came with his approach (success with growing some of the hobby’s most difficult plants, controlling algae, attaining previously ‘impossible’ richness of colours and form) and started sharing the news with others. This led to the development of The 2Hr Aquarist, an organization dedicated to providing the tools and resources for enthusiasts across the world to achieve mastery of the freshwater planted aquarium. We have since grown to become a diverse and entrepreneurial team with over 20 years of combined experience in research, product development, international sales and distribution, marketing and communications. Most importantly, we are aquarists ourselves and enjoy the art and science of the freshwater aquarium. We are grounded by facts and empirical results. We use what we sell and practice what we write.
