Clean Sea Lettuce

A fast-growing nutrient sponge!
Sea Lettuce is commonly found on shallow, rocky reefs worldwide. This delicate green algae prefers brightly lit waters with high nutrient levels. Thus, it can quickly reduce concentrations of dissolved nutrients such as nitrate and phosphate in marine aquarium systems. It is regarded as one of the more nutritious macroalgae and is readily accepted by many herbivorous fishes and invertebrates. Clean Sea Lettuce, or similar macroalgae, such as our Clean Chaeto or Pom Pom Macro, is an essential part of any refugium set up! If you're looking for everything you need to get a new refugium up and running, check out our Ultimate Refugium Starter Pack!

This should seem reasonable enough, as representatives of this sizeable fish family (Acanthuridae) are found in abundance in pretty much every shallow water coral reef ecosystem on Earth. But their strong presence in the …

Phytoplankton

The first link in a food chain is always a primary producer (i.e. algae, plants, various types of bacteria). This is because all other living things—consumers—are incapable of synthesizing organic substances from inorganic ones. Primary producers rely on inorganic sources of energy (sometimes chemical, but usually from light). Using this energy, they take substances such …

Phytoplankton, Macroalgae, or BOTH?

As marine aquarists, we might think of algae as being divided into three (maybe four) distinct categories: the benthic (i.e. bottom-dwelling) microalgae, the open-water microalgae and the macroalgae. The first group consists of the film/turf-formers, the second group consists of the phytoplankton and the third group consists of the larger, plant-like seaweeds. The first group …
