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!

However, we do not guarantee that this item is completely and totally free of anything unwanted.

I couldn’t get any growth of LFS cheato in my fuge under 24 hour Par 32 lighting. No growth in 4 weeks. I purchased your tennis ball sized cheato and sea lettuce; in two weeks it has more than doubled in size under the same conditions. I can’t really account for the change in growth, other than perhaps the health of the sample to begin with, but I can say that Algae barn cheato is growing like mad and significantly reduced my nitrates! Thanks!

This arrived as described, well packaged, and is doing well in my tank! It looks great and appears to be growing already.

I’m converting my tank to Triton so I needed to add a decent sized refugium. I have a mix of algae and added ulva to see if it could serve double duty by feeding to my fish. I typically feed dry seaweed on a clip and I changed to feeding ulva. They seem to like it. The yellow tang especially, but my powder blue tang, flametail blenny, and diamond goby like it too. However not as much as the dry seaweed. I must say, this algae is incredibly fast growing. I ordered a golf ball size and it’s massive now… I only put in my tank less than a week ago. I’m going to need to keep this ulva under control and be sure I harvest it often.

I’m using a light in my refugium specifically for growing algae and this sea lettuce grew 10x it’s weight in 2 weeks. I can not believe how fast this grows and how well it’s doing at removing nutrients from my tank. Not sure if it’s a co-incidence, but I battled a diatom outbreak for months and nothing stopped it expect for adding this to my refugium. The diatoms disappeared from my display tank in 2 weeks! Also, my refugium would fill up with hair algae in about a week, but once I added this to it it’s the only thing growing in their now. It really turned my tank around. Other changes I noticed to the tank after adding this is no hair algae in the display tank, PH raises nicely when I turn on the refugium light, less glass cleaning, and I have been able to remove my filter socks. Only downside (if you’re struggling to find one!) is that my fish won’t eat it.

What is a Planted Marine Aquarium?

The cultivation of saltwater plants is nothing new. It has been fairly common for hobbyists to keep marine “plants” (more often macroalgae than true vascular plants) since the 1980s. Even so, we’ve seen very few aquarium systems that are built and maintained primarily for the display of marine flora. Indeed, to date, the vast majority …
