Chaetomorpha, or Chaeto, is by far the most popular choice of macro algae for growing in refugia. Many reef keepers find this an effective strategy for controlling nutrients.
We recommend high light and high flow to maintain the Chaeto in a healthy condition and maintain nutrient export.
We grow our Chaeto exclusively in FISH-FREE systems so you can be confident you won’t get fish parasites along with your algae. Just clean, healthy Chaeto. You may find copepods, isopods, or other small crustaceans clinging to the strands, but no parasites or pests.
This product is sold in 50-g (wet weight) portions, packaged in 1 pint of seawater. This is approximately the size of a baseball. See the photos for an example of a single portion. Aside from minor variation in color from batch to batch, yours will look more or less just like these images.
