🌿 Chaetomorpha Spiralis (Chaetomorpha spiralis)
Spiral Green Macroalgae • Natural Nitrate and Phosphate Export • The Reef Keeper's Refugium Essential
 
📋 Chaetomorpha Spiralis, or Chaeto, is the go-to macroalgae for natural filtration in marine and reef aquariums. Its coarse, spiral green filaments grow into a dense, springy tangle that soaks up excess nitrates and phosphates as it grows, helping keep your water clean, clear and stable while starving out nuisance algae. Every time you harvest a handful, you remove those nutrients from your system for good.
It's easy to keep and quick to grow. Place it in a refugium or sump with good light and flow to keep it gently tumbling, and it thrives with very little effort. The dense mass also becomes a safe haven for copepods, amphipods and other beneficial microfauna, giving your reef a natural live-food supply.
It's a marine macroalgae, suited to saltwater reef and marine aquariums.
