This plant is beautiful, but not hardy. It needs a lot of light, and is calcerous. Also known as Tufted Joint Algae, it displays delicate bright green pompoms. As the plant grows, a new shoot comes out of the center of the tuft of green, and the fronds fall away to show a new segment beneath the new pompom. Watching it grow over time, the branchs increase in segments.
Most fish won't find this very palletable, and would be a nice addition to a planted biotope of seagrasses. It likes moderate flow, and doesn't extend problematic roots.

When setting up a refugium, it is usually for the purpose of growing macro algae to absorb nutrients (lowering nitrates) plus photosynthesis provides oxygen and depletes CO2. Chaetomorpha is a great macro to use, because it doesn't have a problem of 'going sexual' and grows nicely. If you can't buy Caulerpa, this is a great alternative. Even if you have Caulerpa, you might consider switching to this as I have.

As an indication that your water quality and lighting is good, Coralline Algae will grow nicely. It will cover most anything, from Live Rock to snail shells, usually appearing first on plastic (pumps and plumbing). Seeing tiny dots appear on equipment in my tank, I was so excited to know I had the ratio right. If you scrape any off the glass walls of your aquarium, the chips will 'seed' your tank for more growth. Use a credit card on acrylic to avoid scratches. Reef safe.

Bubble algae - Valonia spp. - annoys people as it spreads into their aquariums. Normally deep green in coloration, these hardened bubbles spread throughout the system. Feeding off nutrients as well as lighting, if left unchecked it can choke out corals. Manual removal is one method, using forceps to pluck them off rocks or plastic fittings. Emerald crabs will consume them. If the aquarium is large enough to house bigger fish, Naso tangs and Foxface fish will eat valonia. Reduced phosphate and nitrate level will weaken this plant's grip on rock.

This is Feather Caulerpa - it grows runners, puts down roots, and is recognized by these "leaves" standing straight up. It can be a pretty display for a Seahorse tank, perhaps. Not the best choice for nitrate absorbtion. It will grow nicely and isn't as prone to "going sexual" as other Caulerpa species. I wouldn't recommend putting this in the display tank, nor would I feed fish in the display this macroalgae since undigested matter could take root in the rockwork.
