Keeping an aquarium thriving takes hard work and evolving knowledge of your system. If you want your aquarium to thrive for years to come, you need to start with a good foundation – your water quality. You are taking care of water, and the inhabitants you choose take care of your water — if you choose wisely. The right inhabitants will work in tandem to keep the nutrients balanced in your system.
Whether you care for freshwater or saltwater, Fish Tank Advisor has resources for you. Find information on algae & PH control, species care, how-to guides, and more. We only recommend products and methods that work or have worked for us.
