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!
