“We will take care of you and make it right”

If for any reason you decide something isn’t quite ultra grade, simply snap a photo of the unopened item(s) you would like replaced. Be sure to get the expiration date on the back label in the photo. After that, visit and submit the form. We’ll review the photo and have a replacement out to you faster than a six-line wrasse at feeding time.

Captive Bred Fish: We guarantee every Live Fish we ship to be 100% Alive On Arrival and we also offer a 7-day health guarantee on all Live Captive Bred Fish.

If the fish is DOA, we will offer you a choice of either a full refund or a free replacement, including the shipping cost.

We can offer this industry leading guarantee on all of our live fish because Captive Bred fish are generally healthier and hardier than their wild-caught counterparts!

Creates excellent biogenic microhabitat for copepods and amphipods!

This hardy, green algae is commonly used in refugia & algae scrubbers, where large masses can be kept with minimal packing. It grows in long, curvy, rigid strands that create a framework with ample inner space that provides shelter for a diversity of small, beneficial benthic creatures such as copepods.

Clean Chaeto, or chaetomorpha macroalgae, such as our Clean Sea Lettuce 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!

PLEASE NOTE: We go to great lengths to treat, quarantine and remove any unwanted parasites, hitchhikers, and other organisms from our macroalgae. However, we do not guarantee that this item is completely and totally free of anything unwanted.

    I made the mistake of buying chaeto from another company before ordering this. The first company sent chaeto filled with hair algae and bubble algae. After a quick inspection I knew there was no chance of that going in my tank I ordered AlgaeBarns Chaeto. This is a much better product that what I received from the other company. What I received is also extremely dense and not stringy like the other stuff I got. I am really impressed with the quality, density and cleanliness There didnt appear to be anything caught in the algae and as described it is clean.

    Arrived clean and green. Very health looking Chaeto. A great addition to my refugium. I love the plastic Algae Barn jars when I get them. They come in handy around the aquarium.

    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!
