Benefits of Using Nualgi Aquarium

When you supplement your regular maintenance routine with Nualgi Aquarium, you will be able to:

  • 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!
  • SEE MORE – By 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!

I give it 5 out of 5 rating and highly recommend the use of Nualgi! I have not done a water change in a month and so far everything is perfect!

What a difference since I went to the daily treatment, I’m finally reclaiming my tank back thanks to Nualgi. I will always use it!

I would definitely recommend Nualgi if you have a problem in your tank and you want to get your tank stabilized.


Before I started Nualgi my tank was absolutely filled with hair algae. I have now got most of it to go away & my corals have never looked better with great extension & color.
