When You Supplement Your Routine With Nualgi, You Will…

  • SEE MORE –  Reducing nuisance algae growth on glass and in your tank, Nualgi improves water clarity and visibility to reveal more of the tank’s environment and its inhabitants.
  • FEED LESS – By restoring missing nutrients, Nualgi brings balance to the natural marine food chain from the bottom up by promoting the growth of diatoms and zooplakton – free food for your fish and corals!
  • CLEAN LESS – Nualgi controls and prevents the growth of nuisance algae as diatoms produced by Nualgi out-compete bad algae for nutrients and increasing dissolved oxygen (DO) levels, improving water quality  –  fewer water changes!
  • WATCH YOUR TANK FLOURISH – Nualgi Aquarium will significantly improve your coral and fish health and longevity, and our trials have shown Nualgi Aquarium can kick start new coral growth in as little as 1 week!

    Setting up an aquarium and fillnig it with saltwater fish can be an entertaining, relaxing and fulfillnig hobby. Keeping your own slice of the ocean in your home and recreating that piece of the reef can provide hours of enjoyment for you and your family (kids love watching fish too). Saltwater reef fish are some of the most beautiful animals in the world, often displaying exotic colors, beautiful flowing fins and interesting, sometimes down-right quirky behavior. If this is the first time you are considering setting up a tank to keep saltwater tank consider reading up on it Yes it is more expensive but it is no harder then a freshwater tank. It depends on you ability to maintain your system. I have been in this hobby for a long time and help people all over the world. Email me if you need more answers.
